Like many industries the balance between cost, stiffness, strength and weight is critical in sports equipment. This study goes through the methodology to perform topology optimization with Catia (CAD), Abaqus (FEA), Tosca (Topology Optimization) and Simpoe (Injection Molding). Topology optimization evolves the geometry to remove unneeded material effectively minimizing weight and maximizing performance. This is carried out by automatically scaling individual element’s density and stiffness based on the stress state of the previous simulation. This is an iterative process where material flows to regions to satisfy constraints and minimize the objective function.

In designing a kinetic mechanism for modern complex structural members that include a rubber device, it is of technical importance to improve the accuracy of predicting the inelastic cyclic behavior of rubber materials. A simple term like “dynamic spring constant” is no longer adequate to describe advanced industrial applications. This paper describes our experimental investigations and numerical simulations of the dynamic characteristics of rubber materials. The experimental dynamic responses, with strain amplitude, temperature dependence, or frequency dependence, were provided by simple shear test specimens as well as by automotive rubber bushings

C-chip capacitors are known to undergo flex cracking during passive bending tests, and would undergo burnout when current passes through it. In general post-impact functional test is considered to be sufficient to establish if a system can withstand a set of drops as prescribed by the standards. A case of capacitor burn-out during post-impact functional test has been taken up for the current study. With an objective of understanding the system dynamics and the mechanics of failure, explicit dynamic simulations were done. Simulations could predict existence of strain peaks possibly exceeding the failure limits considered and existence of displacement hinges postdrop. The orientation of the c-chip was altered taking hints from the simulation. Further testing did not produce any system failure in post-impact functional tests. The paper discusses the methodology adopted in the current study and its limitations from the perspective of predicting failure.

We used the smoothed particle hydrodynamics (SPH) approach in Abaqus/Explicit to simulate sloshing of a partially filled container for a consumer product application. Due to violent sloshing, we did not use conventional methods such as Volume of Fluid (VoF), which is suitable for less extreme deformation of fluid. We investigated the effect of fill level and acceleration on sloshing. Our results indicate that, under severe impact conditions, the maximum sloshing forces are proportional to the mass of fluid and do not scale with acceleration. We also compared the response of the containers with and without baffles. We showed that the container we considered with conventional baffles experiences the lowest maximum stress during sloshing.

The packaging industry is on the brink of process change—including manufacturing, materials and their applications. New concepts are being born via computer screens and virtually nurtured to create commercially-viable packages. This is taking place before ever touching the mold, creating an actual package or conducting a physical test. It’s important to understand various aspects of processing, material properties, package design, product characteristics, as well as specifications and performance parameters that need to be met.

Heat generation in rubber is a complex phenomenon that occurs when a rubber component is being cyclically loaded. The development of this heat build-up comes from the viscoelastic nature of rubber compounds that occurs during the loading and unloading processes, and it is a difficult mechanism to quantify numerically. A lot of research on this particular and characteristic behavior of rubber has been done essentially since the invention of rubber. Over the course of the last decade or so, there have been numerous breakthroughs in the area of heat generation, and finite element codes are beginning to provide solutions to study this behavior. However, it is still a very complex parameter to measure and validate for practical purposes. As a result, an alternate way to devise a method to improve the designs of treads in our tracks against the development of heat build-up is to study the strain energy. The purpose of this research is to understand how we can use the strain energy generated under one full load cycle and utilize this to design a new and better generation of treads that can meet the constant increasing demands for performance in the world of rubber tracks.

This research work follows our first work presented in Simulia 2015 [1] about the modeling the mortarblock assembly for analyzing the potential occurrence of mechanical problems at interfaces as the consequence of an eventual incompatibility. The study considers a heritage building located in Morocco. In this recent study the authors test the effect of non linear behavior of materials and interface. An elastoplastic model including contact with friction and thermal conductivity is used. One concrete numerical example using Abaqus code will be treated and showed on this paper.

This study presents a numerical simulation strategy developed for strength analysis of thermoplastic containers. The method is based on the finite element analysis of both, the blowmolding process and the in-service loadings. The blow-molding analysis is performed to get the molded shape thickness distribution. The parison thickness and the coefficient of friction between the parison and the mold cavity are treated as parameters. They are varied until a good estimate of the thickness distribution is achieved. The thickness distribution obtained from the blowmolding analysis is then used in the subsequent loading analyses on the finished product.

Every year, significant development effort is put into GPU Acceleration of the Abaqus solver. However, the majority of published benchmarks, only highlights very large dynamics models. In this document, we discuss our findings in terms of performance benefits of GPU computing for a range of medium-sized problems with Abaqus 2016 as typically encountered in a Small Business Environment.

Accurate simulation of metal casting press-forming process needs to consider mutual coupling effects in a number of different fields of physics subsystem. Hydraulic systems, control systems and mechanical systems are the most important subsystems among them. It is difficult to create various subsystems in detail in a single modeling tools, so co-simulation technology is used to take advantage of different tools to achieve the entire physical process of system-level simulation. The paper researched the co-simulation in the Abaqus software and the Matlab software based on FMI standard, considered fully the coupling effect between different system, simulated the metal casting press-forming process. The simulation results showed that co-simulation based on FMI standard can be well suited for multi-disciplinary co-simulation in complex mechanical model, and played a well-guiding role in the engineering design. The co-simulation would take more computation time than traditional simulation, but it can be achieved to research the integrated features of system and to reduce greatly experiments costs and prototype trial risks by using this technology.

This paper presents an in-depth spotweld study that involves three different spotweld specimens: KSII; lap shear and peeling, for automotive steel grades and usual part thicknesses for each steel grade. The specimens are welded using automotive welding guns to ensure the representativeness of the samples following automotive standards during the manufacturing process. KSII specimen provides accurate information regarding the local spotweld properties. KSII specimen is tested considering three loading conditions: pure shear, pure tension, and 45 degree mixed-mode. Lap shear and peeling specimens represent the typical joining geometry for spotwelded steel parts (e.g. flange welding).
