This harmonic pressure validation case belongs to solid mechanics. It aims to validate the following parameters:
The simulation results from SimScale were compared to the numerical results in [SDLV124]\(^1\).
Find below the plate geometry used for this validation case:
The geometry is a thick rectangular plate made up of steel.
The node coordinates are tabulated below:
| A | B | C | D | E | A’ | B’ | C’ | D’ | |
| x | 0 | 0.35 | 0.35 | 0 | 0.1575 | 0 | 0.35 | 0.35 | 0 |
| y | 0 | 0 | 0.25 | 0.25 | 0.125 | 0 | 0 | 0.25 | 0.25 |
| z | 0 | 0 | 0 | 0 | 0 | 0.01 | 0.01 | 0.01 | 0.01 |
The node E will be used to compare the results between SimScale and [SDLV124]\(^1\).
