First example is linear static analysis. This is my first post, Im going to start with easy.

This example is from undergraduate class

 

Cantilever beam

 

The cantilever example through Hypermesh.

 

Cross section of cantilever beam

The cantilevers has I-shaped cross section.

 

Run Hyperworks

 

After running, select OptiStruct in the user profiles

 

First, drow a line

Geom - lines

Start point : 0, 0, 0

End point : 5000, 0, 0

 

 

Create - BeamSection

define parameter

Beam section

 

Create - Materials

Card Image : MAT1

MAT1 : generally used linear-elastic

E : 210000

NU = 0.3

Materials

 

Create - Properties 

Card Image : PBEAML

-PBEAML : described information of beam section

Material : (1) matarial

Beam Section : (1) beamsection1

Properties

 

Components

Property : (1) property

 

second, create a mesh

1D - line mesh 

line mesh

element size : 300

property : property1

components : 0, 1, 0

 

1D Traditional and Detailed Element Presentation

 

 

Third, define the constraints

Create - Load Collectors 

Name : spc (single point constraints)

 

BCs - Create - Constraints

Constraints

Check All dof and select left node

 

Define a load

Create - Load Collectors

Name : force

 

BCs - Create - Forces

magnitude : -200 kN

axis : z-axis

 

Select the right node to define load

 

Finally, set the load case

Create - Load Steps

Analysis type : Linear Staric

SPC : (1) spc

LOAD : (2) force

Load steps

 

Analysis - OptiStruct

export options : all

run options : analysis

memory options : memory default

 

The maximum displacement(z) is 785mm

In element stresses, we can see values at specific parts of the section geometry.
