Home / Examples / Stress Analysis [Galileo] / Example 3: Cantilever with Forced Displacement
The free end of a cantilever is displaced forcibly.
The distributions of displacement and stress are solved.
Unless specified in the list below, the default conditions will be applied.
Results will vary depending on Femtet version and the PC environment.

N/A |
The bar is a rectangular solid body. The material is polycarbonate.
The boundary condition of fixed displacement is set to the fixed face of the bar and
the boundary condition of forced displacement in the negative Z direction is set to the edge topology of the other face.

The contour diagram shows the magnitude of displacement.
The displacement in the -Z direction is greater towards the tip of the bar. At the tip of the bar, the -Z displacement of approximately 500 um occurs.
The vectors of the stress are shown below.
The upper part of the fixed end is getting the tensile stress, whereas the lower part is getting the compressive stress.
The external force and reactive force are listed in the table below.
The reactive force at FIX is 445 [N] in +Z direction.
The external force at DISP is 445 [N] in -Z direction.
