 Model

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.

Boundary Conditions

Boundary Condition Name/Topology	Tab	Boundary Condition Type	Settings
FIX/Face	Mechanical	Displacement	Select all X/Y/Z components. UX=0, UY=0, UZ=0
DISP/Edge	Mechanical	Displacement	Select the Z-direction component. Uz=-0.5x10-3 [m]

Results

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.
