Hi!!

We generally encounter governing equations of even order. In FE formulation we get a symmetric coefficient matrix 'A' (AX = B). I have a few doubts as follwing.

[a] Any odd order governig equations ? If so, you may please write.

[b] Say, it has a functional also, then, what's the order of that differentiation?

to treat the shear locking phenomenon

hi, everybody

i am going to simulate crack propagate by ABAQUS, but i haven't used ABAQUS before.

now i have two problems:

 1) can abaqus calculate the velocity of crack advancing?



 2)FGM(functionally graded materials ). material property varies at

 different position,such as density ,modulus, possion ration. can

 abaqus deal with this problem by umat .

thanks.

Dear Researchers and Industry Engineers, 

In this letter I am looking for some comments and industrial supports for my PhD research on non-contact measurement for machinery maintenance.
