Composites Capabilities Expanded at Altair with CEDREM Partnership

Centre d'Expertise en Dynamique Rapide, Explosion et Multiphysique, SAS (CEDREM) has joined the Altair Partner Alliance (APA), adding CEDREM’s KTEX Family of integrated numeric tools for composites to the APA.

"CEDREM is specialised in finite element simulations representing high speed phenomena (such as impacts, ballistics, explosion or blast) and composite behaviour,” said Karine Thoral Pierre, CEO at CEDREM. “To improve our models, tools representing the composite materials at the mesoscale and taking into account the manufacturing processes were needed. The KTex Family meets this need. We improved our material laws and cut down the gap between simulations and reality. We are pleased to share those tools with the Altair community."

KTEX Family is a suite of numerical tools that analyse the behaviour of composite materials during the manufacturing process. It is comprised of four modules: KTEX Pattern, KTEX Layup, KTEX Winding and KTEX Woven Property, all of which work at the scale of composite yarns, or the meso scale, and address specialised parts of the optimisation and manufacturing process. KTEX Pattern models the exact geometry of any given weave while KTEX Layup simulates the behaviour of that weave during the layup process. KTEX Winding visualises the weave during the winding process and KTEX Woven Property calculates the homogenised mechanical properties for any given weave.

“KTEX Family offers complete analysis and optimisation of composite weaves and the effects that the manufacturing process has on them,” said Shan Nageswaran, Senior Director, HyperWorks at Altair. “Looking at materials on the meso scale allows engineers to achieve a completely new perspective, especially in relation to ballistics, that Altair customers will find especially valuable. We are really looking forward to further collaboration with the CEDREM team.”

Integrated completely with HyperMesh, Altair claims users are able to model weaves in any dimension (1D, 2D, 3D) using all fibre and matrix materials available. Highlights of the software capabilities include representation of customised weaves with bespoke fibre and matrix materials and prediction of the impacts of the manufacturing process on the final part. Users are also able to optimise the weaving pattern as well as the manufacturing processes necessary to produce it. While composites modeling is necessary and applicable in many industries, KTEX Family is especially suited for those in automotive and performing ballistics.

To learn more about CEDREM and KTEX Family, register for the introductory webinar on 29 October 2015 at 9 a.m. EDT and 1 p.m. EDT, or visit the CEDREM solution page.
