Abstract
Join the webinar on February 13th 2014 for a discussion on how GENOA can be used to couple different analysis types together using different FE solvers so that advanced structures can be analyzed and assessed for damage initiation and propagation, fracture initiation and propagation using the engineering technology of choice.
Knowledge of the residual strength of a composite after a possible damage event is important. It allows the engineer to asses many ‘what-if’ situations in order to make a robust design.
Using GENOA, damage, residual stresses, and deformed/fractured meshes from one type of analysis type and solver can easily be used as the starting point for a completely different analysis and solver. This allows the residual strength of a structure to be computed based on a customized user defined life cycle for a structure all with users choice of technology.
An example will be shown that simulates impact with LS Dyna and then tension after impact using OptiStruct. Damage and residual stresses after impact and used to begin the tension after impact analysis.
We will also show our MULTI-SCALE methods carrying FE results down to the micro scale level so that the root damage mechanisms are assessed and the resulting degradation is accurately represented for every finite element and for every load step in the analysis.

Abstract
Join the webinar on March 13th 2014 for a discussion on how GENOA and MCQ can be used to determine the effect of voids, defect shapes and sizes, and fiber waviness on fatigue life. Using this methodology advanced structures can be analyzed and assessed for damage initiation and propagation, fracture initiation and propagation.
Knowledge of the life of a composite structure with defects is important since it reflects the “as-is” condition. It allows the engineer to assess many types of internal defects, their distribution, shapes, and size, in order to make decisions and produce a robust design.
An example will be shown that simulates these effects on an open hole tension coupon undergoing quasi static fatigue as well as random fatigue.
We show our MULTI-SCALE methods carrying FE results down to the micro scale level so that the root damage mechanisms are assessed and the resulting degradation is accurately represented for every finite element and for every load step in the analysis.
Title: 1D, 2D, and 3D, Unidirectional, Weave, and Braid Modeling and Reverse Engineering Constituent Properties for Use in Multi Scale Progressive Failure Analysis

Abstract
Join the webinar on April 10th 2014 for a discussion on how GENOA and MCQ can be used to determine the constituent properties – fiber, matrix, and stress strain curves for unidirectional composites. We will also discuss how to model weaves and braids. These 1D, 2D, 2.5D and 3D architectures can be used in FE solvers to assess for damage initiation and propagation, fracture initiation and propagation.
Material, damage, and fracture modeling is a very important step in finite elements. We will begin by discussing the material modeling for complex architecture and the damage and fracture criteria used to model progressive failure analysis.
An example will be shown that models 1D, 2D, and 3D architecture for a simple coupon and then uses that to perform a progressive failure analysis of an automotive vehicle component.
We show our MULTI-SCALE methods carrying FE results down to the micro scale level so that the root damage mechanisms are assessed and the resulting degradation is accurately represented for every finite element and for every load step in the analysis.
