Example 24 : Stress Analysis of a Tool

General

• A tool has two holes and has them fixed. The force is applied at the tip of the tool.
   

• The deformation, the displacement distribution, and the stress distribution are solved.
   

• Unless specified in the list below, the default conditions will be applied.

Model

The material is iron.

The inner faces of the holes are fixed by boundary condition.

The force is applied on the top face of the tool by the distributed face load boundary condition.

Boundary Conditions

The value of distributed face load is set assuming that a total of 100 kg is applied to the tip face of the tool.
The area of the tip face: 0.0052x3.14=0.0000785 m2

Total load: 100×9.8 = 980 N

Distributed load: total load/area of front face: approx.12484076 N/m2 (= Pa )

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
LOAD/Face	Mechanical	Distributed Face Load	X=0, Y=0, Z=-1.2x107 [Pa]

 

Results

The Z-direction displacement is shown below by contour. The contour diagram shows the magnitude of displacement.

The displacement in the -Z direction is larger towards the tip of the tool.

 

The vectors of the stress are shown below. The unit is [Pa].

The upper part of the tool is getting the tensile stress, whereas the lower part is getting the compressive stress.
