Progressive failure model for 3D analysis of FRP structures

In our Resources page, you will find a UMAT (user-defined material model) developed in the CORE Group. This UMAT was developed for integration with the ABAQUS FEA software suite, implementing a novel progressive failure model for the 3D simulation of pultruded FRP structures. With this approach, it is possible to model the orthotropic laminates as a homogeneous material. You may find more information in the UMAT page. Feel free to use this UMAT in your work, but if you do so, please cite us: J.A. Gonilha, N. Silvestre, J.R. Correia, V. Tita, D.

Support from PCE Instruments

Taking quick and accurate measurements of air temperature and relative humidity is an essential part of conducting experimental work in our composites lab. To aid us in this task, PCE Instruments has recently provided us with a thermo hygrometer (PCE Instruments - Thermometers) that can accurately measure temperatures and relative humidity between -40 °C and 125 °C. The support of PCE Instruments is gratefully acknowledged by the CORE Group.
