f(I1,J2)=J2−αI1−k=0f of open paren cap I sub 1 comma cap J sub 2 close paren equals the square root of cap J sub 2 end-root minus alpha cap I sub 1 minus k equals 0 I1cap I sub 1 is the first invariant of total stress, J2cap J sub 2 is the second invariant of deviatoric stress, and are material constants mapped to

Softening materials can lead to mesh dependency, where failure zones narrow down to the size of a single element. Regularization techniques (like non-local or gradient plasticity) are needed to mitigate this. 6. Practical Applications in Geotechnical Engineering fundamentals of plasticity in geomechanics pdf
