    Natural frequency of a damped system, oscillated with a sinusoidal displacement

    Hi! I have the following system: x is am imposed motion and y is the output that I obtain. I would like to calculate the natural frequency of the system. My intuition says that it is equal to sqrt((K+k)/m), but I am not sure how to derive this value from the equation of motion of the...

    Parameters for linear Drucker Prager

    Hi, I want to model the compression of a polymer cylinder. For that purpose, I want to use a linear Drucker Prager yield criterion with no hardening and a non-associative flow rule.  I have seen that in Abaqus the linear Drucker Prager requires the introduction of three parameters: friction...
