Case Study: Predicting Virtual Allowables

During the process of designing lightweight CFRP structures, one usually needs access to allowable values. However, allowables generation is particularly costly and time-consuming. Each characterized material system must cover various layups, coupon tests, and environment conditions. Each test configuration must be repeated many times to obtain a statistical evaluation of the mechanical property. With advanced ...

Value of Simulation to Material Testing and Development

This article was originally posted by Bob Schmitz, Senior Business Development Manager for e-Xstream engineering on Composites World magazine. Traditionally we have designed, characterized new materials with physical testing by using simple coupon tests, which are affordable and the results have generally been accepted as fact, even if the sample size is small. However, material science has ...

Composites in the Automotive Industry: Forum and Workshop October

Some of the most significant challenges facing the automotive industry include raw material cost, light-weighting and achieving mass production. These are direct consequences of environmental requirements becoming more rigorous as concern about carbon emissions grows. Moreover, the use of carbon fiber is an important part of the answer to these problems but brings on its own set of issues that need to ...

Multi-Scale Simulations With Marc and Digimat

Composite materials of various types (unidirectional composites, short fiber reinforced plastics, nano-composites, ceramics, etc.) exhibit highly nonlinear, anisotropic, strain-rate and temperature dependent properties in mechanical, thermal and electrical fields. They often exhibit enhanced performance with respect to density as compared to traditional structural materials. However, simulating composite structures is complicated, and usually requires a micro-mechanical, ...
