shear strength of saturated clay


Hello, 

My class and I performed a unconfined compression test which ended up creating a 50 degree angle of failure on our sample of clay. I am unsure about this question could you please help me. 

Can you infer a failure plane orientation based on the envelope ? How does your observed failure plane compare with your envelope?

This is likely to have been an undrained strength so in that case you could have gotten an Su not friction angle.
