Researchers at Morocco’s University Hassan First were faced with compatibility problems when replacing centuries old masonry with modern construction block and mortar while restoring heritage buildings. Realistic simulation with Abaqus FEA software from Dassault Systèmes’ SIMULIA helped the university identify internal compressive stresses between dissimilar materials.

In this paper, a drone propeller is used as an example to illustrate the print failure modeling strategy. The commercial finite element software package ABAQUS is used to simulate the FDM printing process and in-service performance of the propeller. In order to analyze the printing process, a heat transfer analysis is done first to predict the temperature history of the part, which drives the stress analysis for distortion and residual stress predictions. The tool path patterns dictate how material is added during the printing and it also have direct influence in the residual stresses in the part. Abaqus uses machine tool path as a direct input and solves the local orthotropic material properties and evolving cooling surfaces using the event series and progressive element activation technologies.

A multiscale modeling procedure was presented to design thermosetting resins and products of polymer composites. Heat curing and cross-linking reaction steps were considered with activation energy and heat generation via molecular dynamics simulation of BIOVIA Materials Studio. The mechanical properties and adhesive strength for fillers were also estimated, and were assigned to SIMULIA Abaqus. Using the Abaqus fracture analysis capability, the crack propagation behavior, including matrix-failure and interface-failure, was investigated.

This work presents a coupled fluid-structural interaction (FSI) capability wherein pressure and thermal loads predicted by the CRUNCH CFD and CRAFT CFD Navier-Stokes solvers are exchanged with Abaqus/Standard and Abaqus/Explicit using the Co-Simulation Engine (CSE). Multiple domains may be simulated concurrently, on separate groups of processors. Data exchange is handled through SIMULIA’s Co-Simulation Engine API. The boundary surface common to the fluid and solid domains is defined, along with the specific scalar and/or vector fields to be exchanged. Point forces or pressures, heat fluxes, displacements, and temperatures are passed between the codes, and simulations may be either one-way or two-way coupled. Applications of the FSI simulation capability to problems of interest are presented and discussed.

In aircraft bleed air system ducts, cracks may exist or initiate from manufacturing defects in areas of high stress concentration in particular at welds. The initial minor cracks may grow into two possible failures: either the crack grows steadily through the wall to form a stable “through-crack” (leak-before-break), or it becomes unstable before or after it has reached the opposite surface of the duct wall and spreads rapidly over a large portion of the duct (break-before-leak), depending on the pressurized hot-air load and the toughness of material. For the safe design of bleed air system ducts and assessment of ducts with minor cracks found in the quality inspection, it is required to understand and predict the crack behavior and leak-before-break leakage rate.
