    The ratio of deformation speed to wave speed exceeds 1.0000 in at least one element error in ABAQUS

    I am trying to simulate impact analysis with Car and Crash Barrier in ABAQUS. I used SI (mm) units throughout my modeling. When I run my model, I encounter the following error - “The ratio of deformation speed to wave speed exceeds 1.0000 in at least one element”. The stepwise procedure given in...

    The ratio of deformation speed to wave speed exceeds 1.0000 in at least one element.

    Hello friends! I am simulating an impact analysis. During analysis, I encounter the following error. The ratio of deformation speed to wave speed exceeds 1.0000 in at least one element. This usually indicates an error with the model definition. Additional diagnostic information may be found in...

    How to make two elements strike each other in ABAQUS?

    Hi @NRP99, Thanks for your reply. For your kind information, I have defined interactions as you mentioned. Still, there is no impact happening between the two elements. I have attached the *.cae file for your reference. Please check the files and offer your suggestions...

    How to make two elements strike each other in ABAQUS?

    I have modelled a Beam and Car using Abaqus for impact analysis. During the analysis, the Car passes through (Penetrates) the beam without any impact. Can anyone please give me any valuable suggestions? Thanks in...
