ACT Change material between load steps

---

ACT allows the user to change material of the bodies or elements during solving a problem.

The material properties are supported in Version 1:

• Density(constant or depend on temperature)
• Elasticsity: Isotropic or Orthotropic (constant or depend on temperature)

Tree outline

The bodies or elements are selected by Named Selections.

Test problem:

• Fixed at bottom face
• Applied Pressure on the top face of body
• Initial, assign the Structural Steel for the body
• Use ACT to change one third in the middle to Polyethylene, one third in the right to Aluminum Alloy

Details of the ACT Change Material

Change one third in the middl to Polyethylene at load step 1

Change one third in the right to Aluminum Alloy at load step 1

Results

• Total Deformation

• Material number
