Simulation of Glue Shrinkage

In bonded or glued assemblies the shrinkage during cure can be an issue. It may result in misalignment problems or high loads and stresses in the various parts. A simple technique may be used to simulate this by modifying the material Coefficient of Thermal Expansion (CTE) and applying a global temperature load. The bonded parts should be assigned a zero value for the CTE. The glue will use some real number. The relation between the applied temperature load, glue CTE and percent shrinkage is shown as follows:
