Figure 5:

Once the FE material coefficients were optimized, fluid pressure results were compared between static and dynamic scenarios. Fluid pressure measured at the element of maximum compressive strain experienced significant depressurization in the static case (−11.6% from 0.259 MPa at loading compared to 0.229 MPa after 600 s), while the peak fluid pressure during dynamic loading remained constant (approximately 0.259 MPa). 150 s out of 600 s total is shown for better visualization.
