Determine the mode of failure of a composite

Carrie Martin

Hi 

 

I am outputting the composite strength ratios of a composite in hyperworks. 

I know the component is failing but I want to know what the mode of failure is. 

I am pulling out the stresses of the elements and want to compare it to the allowable that are inputted in the material deck. 

Is there a method to find out how to find out the mode of failure.

Hello,

You can use some failure criteria to evaluate this. Here are some links that might be useful:

Composite Stress Toolbox

MATF

Thanks
