Multi-scale material modeling for additive manufacturing

While additive manufacturing of reinforced polymers is appealing and increasingly considered for production of actual parts, major obstacles must be overcome by engineers. Dimensional accuracy of the part must obey to strict tolerances that may not be met due to thermally induced part distortion or poor surface roughness. On the material side, an anisotropic material behavior is brought in by the specific 3D printed layered architecture and oriented reinforcements. This process-induced material behavior make the part mechanical response challenging to predict.

Therefore, Digimat, the material modeling platform, can offer you a solution to overcome your challenges.

Case Study: Predicting Virtual Allowables

During the process of designing lightweight CFRP structures, one usually needs access to allowable values. However, allowables generation is particularly costly and time-consuming. Each characterized material system must cover various layups, coupon tests, and environment conditions. Each test configuration must be repeated many times to obtain a statistical evaluation of the mechanical property. With advanced ...

How to Improve FEA for Progressive Failure Analysis of Composite Laminates

Failure of continuous fiber composites are much more complex than metal. Continuous fiber structure involves most of the time stacking of several plies, each ply being characterized by a single fiber orientation. The intra-laminar failure mechanism is mainly due to delamination, while the inter-laminar failure is governed by various mechanisms like matrix cracking, fiber breakage ...

Realizing the Full Value of Aerospace Composite Design

The complexity of composites vs. traditional metallic materials has forced aerospace manufacturers to complete 7-20x more tests than before across all levels of the validation pyramid. With smaller tests costing around $1k-$5K, and the larger tests costing up to $1M-$3M, a significant barrier has been presented in terms of cost and time to validate their ...
