FEM simulation of shear wave propagation
FEM simulation of shear wave propagation
(OP)
Hi everyone,
I am trying to simulate wave propagation in a purely elastic medium. I am not using any software and trying to write the process in MATLAB.
For my problem, a nearly impulsive body force will generated in a localized region the medium, this will create a disturbance in the medium. Over time, this disturbance will propagate away from the region of excitation. The displacements are on the order of 1 micron. I am using newmark time integration technique. My results seem to be fine for first several time steps. But, over time the wave seems to become diffuse. Can anyone tell me the reason for this?
