OS-T: 1000 Linear Static Analysis of a Plate with a Hole
This tutorial demonstrates the creation of finite elements on a given CAD geometry of a plate with a hole. Further, application of boundary conditions and a finite element analysis of the problem are explained. Post-processing tools are used in HyperView to determine deformation and stress characteristics of the loaded plate.
Launch HyperMesh and Set the OptiStruct User Profile
Open the Model
Set Up the Model
Create the Material
Create the Property
Update the plate_hole Component
Apply Loads and Boundary Conditions
In the following steps, the model is constrained so that two opposing edges of the four external edges cannot move. The other two edges remain unconstrained. A total load of 1000N is applied at the edge of the hole in the positive z-direction.
Create Load Collectors
Create Constraints
Create Forces on the Nodes around the Hole
Create Load Steps
An OptiStruct subcase has been created which references the constraints in the load collector spcs and the forces in the load collector forces.

View the Results
Displacement and Stress results for linear static analyses are output from OptiStruct by default. The following steps describe how to view those results in HyperView.
HyperView is a complete post-processing and visualization environment for finite element analysis (FEA), multibody system simulation, video and engineering data.
View a Contour Plot of Stresses
- What is the maximum von Mises stress value?
- At what location does the model have its maximum stress?
- Does this make sense based on the boundary conditions applied to the model?
View a Contour Plot of Displacements
- Under Result type set the first first pull-down menu to Displacement (v) and set the second pull-down menu to Mag.
- Click Apply.
- What is the maximum Displacement value?
- At what location does the model have its maximum displacement?
- Does this make sense based on the boundary conditions applied to the model?
