This technical article illustrates the advantages of using virtual simulation to evaluate the thermal processes of die casting to reduce the formation of residual stresses and deformations in the components produced.
Simulation is becoming increasingly valuable in this regard as the geometrical complexity of castings increases to meet market demand for more competitive, higher quality products at lower cost and reduced time to market.

CASE STUDY
The article focuses on the difference in fatigue behaviour between rubber and metal materials. While metal fatigue is often described by a simple rule: increasing mean strain is detrimental to fatigue life, rubber fatigue is more complex and depends on the material's ability to strain crystallize. The text concludes that while tensile mean stresses are always detrimental in metals, in rubber they may be either beneficial or harmful depending on whether the rubber can strain crystallize.
