| Description Progressive damage modeling of composites under low velocity impact, and high velocity impact is of interest to many applications including car crash, impact on pressure vessels, perforation and penetration of thin and thick section composites. This course will provide a comparison between available composite models in LS-DYNA for shell and solid elements, e.g., MAT2, MAT54, MAT59, & MAT162. Among these material models, rate dependent progressive composite damage model MAT162 is considered as the state of the art. This short course will include the theory and practice of MAT162 composite damage model with applications to low and intermediate impact velocities, understanding the LS-DYNA programming parameters related to impact-contact, damage evolution, perforation and penetration of thin- and thick-section composites. Topics Covered in this Short Course: Impact and Damage Modeling of Composites Introduction to Composite Mechanics Composite Material Models in LS-DYNA for Shell and Solid Elements Theory and Practice in MAT162 Progressive Composite Damage Model for Unidirectional and Woven Fabric Composites Comparison between Different LS-DYNA Composite Models Low Velocity Impact and Compression after Impact Applications Perforation Mechanics of 2-D Membrane and Thin Composites Penetration Mechanics of Composites and Soft-Laminates Introduction to LS-DYNA (Document Only) |
