Abaqus Tutorial: LaRC05 Failure Criterion For Fiber-Reinforced Composites

LaRC05 Failure Criterion For Fiber-Reinforced Composites

This “Abaqus Tutorial: LaRC05 Failure Criterion For Fiber-Reinforced Composites” training course provides an overview of the LaRC05 failure criterion and its application to fiber-reinforced composites. Fiber-reinforced composites have become increasingly popular in engineering applications due to their high strength and stiffness-to-weight ratios. However, predicting the failure behavior of these materials can be challenging due to their anisotropic and heterogeneous nature.

The LaRC05 failure criterion is a widely used method for predicting failure in fiber-reinforced composites. This course will cover the theory behind the LaRC05 failure criterion, as well as its implementation in the Abaqus software package. Students will learn how to characterize material properties for use in the LaRC05 failure criterion, and how to validate and verify simulations using this method.

Throughout the course, students will work on examples and case studies to develop their understanding of the LaRC05 failure criterion and its application to engineering problems. By the end of the course, students will have a solid understanding of how to use the LaRC05 failure criterion in Abaqus simulations, and how to apply this knowledge to real-world engineering challenges.

What is the LaRC05 failure criterion?

LaRC05 failure criterion is almost the latest failure criterion that has been developed in the composite industry, and due to its characteristics, it has received more attention from design engineers than Puck, Hashin, Tsai-Wu, etc.

In this criteria, the nonlinear shear response is considered. The proposed criteria have four modes of failure: Crack matrix, fiber failure, fiber splitting, and Kinking. In LS-Dyna software from version R7.0, this criterion can also be used as * MAT_261 and * MAT_262. NASA has supported the development of this project.
