Conferences „Lifetime - Simulation“

„Lifetime – Simulation“

The service life of technical rubber materials is dependent on a multitude of often interlinked influencing factors. An essential component of this seminar deals with the effects of chemical and thermal aging and the complexity of the fatigue properties of elastomers under arbitrary loading conditions. These are viewed in conjunction with approaches to and the […] more...

More transparent LSR processes with Virtual Molding

To Pass a Long Way

As LIM processes can be quite challenging a thorough understanding of not only the part, but of the whole mold and process are essential for molders to stay competitive. With the help of the Virtual Molding approach one can look into the process upfront and make secure decisions on material, mold and process. more...

Improving pressure demand prediction to design elastomer molds

Simulation is an established tool to support the design of elastomer molds. However, the predicted value of the pressure required to fill the cavity sometimes deviates from reality. At DKT/IRC 2015, the Sigma-team, Aachen, will deliver insights on pressure calculations and offer recommendations on how to interpret the obtained results. more...

Simulation of oxidative Ageing Processes in Elastomeric Components

A chemomechanically coupled model is presented which can realistically predict the effects of oxidative ageing processes in elastomeric components. The chemical model is based on a simple reaction scheme, which considers oxygen, antioxidant, and the elastomer. more...
