# Example19Two Plates Adhered at One End (Simple Contact #1)

General

• A bimetal consisting of two different metal plates is analyzed. Both ends of the plates are adhered.
The simple contact boundary condition is set on the inner faces of the plates.The deformation caused by thermal load is solved.

• The deformation, the distributions of 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.

Opt for the thermal load in the analysis condition, 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 25[deg] Step/Reached Temperature Setting Step 1: 50[deg]

### Body Attributes and Materials

 Body Number/Type Body Attribute Name Material Name 0/Solid TERMINAL MAT3 1/Solid PLATE1 MAT1 2/Solid PLATE2 MAT2 3/Solid TERMINAL MAT3

The material properties are set up as follows:

MAT2 has a much higher thermal expansion coefficient than MAT1.

 Material Name Tab Properties MAT1 Elasticity Young’s modulus: 10×10^9[Pa] Poisson’s ratio: 0.3 Coefficient of Expansion 5×10^-6[1/deg] MAT2 Elasticity Young’s modulus: 10×10^9[Pa] Poisson’s ratio: 0.3 Coefficient of Expansion 10×10^-6[1/deg] MAT3 Elasticity Young’s modulus: 10×10^9[Pa] Poisson’s ratio: 0.3 Coefficient of Expansion 0x10^-6[1/deg]

### Boundary Condition

### Results

The contour diagram shows the displacement.

The bi-metal is deformed by the thermal load and a gap appears between the plates.

The diagram below shows the side view.
