Why are all the deformations and strains 0 in my ANSYS LS-DYNA analysis?

Click For Summary
SUMMARY

The discussion centers on an issue encountered in ANSYS LS-DYNA where all deformations and plastic strains are reported as zero after solving a model despite applying high forces. Key factors contributing to this problem include meshing quality, element types, material models, and the application of consistent units. Users are advised to verify the fixed points and the method of load application, particularly in impact scenarios, to resolve the issue effectively.

PREREQUISITES
  • Understanding of ANSYS LS-DYNA software
  • Knowledge of finite element analysis (FEA) principles
  • Familiarity with material models and element types in LS-DYNA
  • Experience with meshing techniques and quality assessment
NEXT STEPS
  • Investigate meshing quality and size in ANSYS LS-DYNA
  • Learn about different element types and their applications in LS-DYNA
  • Review material models and their parameters for accurate simulations
  • Study the impact of load application methods in dynamic analyses
USEFUL FOR

This discussion is beneficial for engineers, analysts, and researchers working with ANSYS LS-DYNA, particularly those troubleshooting issues related to deformation and strain analysis in finite element models.

I want to do an analysis in ANSYS LS-DYNA. After applying element types, materials and loads to my model, I solved the problem. but after finishing the solution all of the deformations, plastic strains and ... are 0. (the applied force is very high and I expect to see rupture in a large area of my model) does anyone face this problem before? what's the result of this problem?

thanks

I'm not ANSYS expert but u may check the meshing quality, size and most importantly in ur case the fixed points
