    ABAQUS random analysis (PSD) - covariance of stress tensor components

    Hello, I am currently using ABAQUS 6.13 to compute the response of a structure to a given acceleration (base motion) of which I know the PSD. The analysis runs without any problem, but I cannot find in the output the cross-PSD (or covariance) between the different stress tensor components...

    Model piezoelectric shunt circuit

    Hello, I am a bit new to ABAQUS and I am trying to model piezoelectric shunt circuits. So far, I was able to model a simple aluminum beam with some piezoelectric elements that represent the actuator bonded to the structure. I solved the system through the "Linear Perturbation ->...
