What is the LaRC05 failure criterion?
This 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 criterion, the nonlinear shear response is considered. The proposed criteria have four modes of failure: Cracks matrix, fiber failure, fiber splitting, and is 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.
In this training video, first, an introduction to failure criteria is given. Then, the formulation and theory of failure criterion (LaRC05) are explained and the methods of using it in Abaqus software are examined.
Finally, two practical examples and 19 useful files on the use of this criterion in numerical modeling in Abaqus are presented.
saber –
It was a useful and novel approach, although this theory only applies to unidirectional fibers, it is better to talk about other failure criteria in the future. thank you
