# Example25Cylinder under Fixed Normal Displacement Subjected to Thermal Load

General

• The model is a cylinder consisting of two different materials
Its normal displacement is fixed and subjected to the thermal load.

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

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

### Analysis Space

 Item Settings Analysis Space 3D Model unit mm

### Analysis Conditions

The temperature is applied evenly on the model.

Select Thermal load and set the reference temperature and the reached temperature.

There is no need to couple with the thermal analysis [Watt].

 Item Settings Solvers Mechanical Stress Analysis [Galileo] Analysis Type Static analysis Options Select “Thermal load”.

The Step/Thermal Load tab is set as follows.

 Tab Setting Item Settings Step/Thermal Load Reference temperature 0[deg] Step/Reached Temperature Setting Step 1: 300[deg]

### Model

The cylinder’s top and bottom faces are fixed in all directions. The side is fixed in normal displacement.

The upper and lower bodies have different coefficients of expansion.

### Body Attributes and Materials

 Body Number/Type Body Attribute Name Material Name 0/Solid Body1 Mat1 1/Solid Body2 Mat2

The material properties are set up as follows:

 Material Name Tab Properties Mat1 Coefficient of Expansion 0x10^-6[1/deg] Elasticity Young’s modulus: 1×10^9[Pa] Poisson’s ratio: 0.3 Mat2 Coefficient of Expansion 400×10^-6[1/deg] Elasticity Young’s modulus: 1×10^9[Pa] Poisson’s ratio: 0.3

### 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 SlideFree/Face Mechanical Normal displacement 0.0×10^-3[m]

### Results

The displacement diagram is shown below. The scale adjustment is “same scale”

Body2 is pushing up Body1.

The section at XZ plane is shown below.

The border has been moved upward translationally.
