UNIVERSITY HASSAN FIRST ARCHITECTURE, ENGINEERING & CONSTRUCTION

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.

Prediction of Printing Failure of a 3D Printed Drone Propeller using Fused Deposition Modeling

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.

Multiscale Modeling of Polymer Composites: From Atomistic Simulation to Structural Analysis

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.
