Model
The disc is a low-height cylindrical solid body. The material is copper.
Distributed load is applied on the top face. The bottom circumference is fixed.

Boundary Conditions
The total load applied on the top face is 980N (100kgf) which is distributed uniformly on the face.
Face area: (23.5/2)2×3.14=433.5 mm2
Total load: 10×9.8 = 98 N
Distributed face load: Total load / Face area = 2.26×105 N/ｍ2 (=Pa)

Results
The Z-direction displacement is shown below by contour. The contour is the Z displacement.
The center area is sinking approximately 7um.
The vectors of the mechanical stress are shown below.
The upper side is getting the tensile stress, whereas the lower side is getting the compression stress.
The external force and reactive force are listed in the table below.
The reactive force at FIX is 98[N] in +Z direction.
The external force at LOAD is 98[N] in -Z direction.
