    Exporting MASS STIFFNESS DAMPING MATRIX in EXPLICIT DYNAMICS

    Hi, Is there any technique to export mass stiffness and damping matrix when using Explicit dynamics Solver as I see that the input Command tab is inactive.

    Doubt about Dynamics of a system from FE analysis

    Hi FEA way, Is this similar when I use a static structural solver in ANSYS. Do I get a similar mass Stiffness matrix for the same equation of motion?

    Doubt about Dynamics of a system from FE analysis

    Hi, Consider a Single link Manipulator of which I am interested in studying the dynamics as a function of state space formulation like x_dot = Ax + Bu or x_dot = f(x) + h(x)u for linear and nonlinear case respectively. So when developing the FE, what solver do I need to consider. As I follow...

    How to extract Stiffness matrix(s) for Non-linear FE Dynamic Implicit case in ABAQUS

    Hi, I am studying the behavior of a soft robotic manipulator with elastomer material like rubber which has nonlinear material behavior. For solving a nonlinear FE case with 'Nlgeom' ON in ABAQUS, the Stiffness matrix and external load vector are updated at each iteration by the relation...

    Extraction of Stiffness matrix(s) in Abaqus for Nonlinear FE case

    Hi, I am studying the behaviour of a soft robotic manipulator with elastomer material like rubber which has nonlinear material behaviour. For solving a nonlinear FE case with 'Nlgeom' ON, the Stiffness matrix and external load vector are updated at each iteration by the relation. [K(x)]x =...
