DTE is launching two new products at NAFEMS UK 2014 (10-11 June, Oxford Belfry Hotel), the UK’s largest independent gathering of simulation and engineering analysis professionals. Recently, DTE has signed contracts to be the sole UK reseller of both CAEfatigue VIBRATION and HyperSizer, solutions that will be of interest to attendees who use FEA code.

CAEfatigue VIBRATION is a revolutionary new frequency domain fatigue solver, which works with mixed random (Power Spectral Density) and deterministic loading sources in a way not currently possible with other software solutions. The avoidance of fatigue failure is a design requirement for nearly all mechanical engineering systems. In fact, for many everyday products like cars, aircraft, trains, etc fatigue life (or durability) is the limiting design requirement.

Therefore, CAEfatigue VIBRATION is particularly relevant to stress or test engineers that use FEA software, such as MSC Nastran, to calculate fatigue in structures which vibrate.

Neil Bishop, managing director of CAEfatigue Limited said: “Powerful, efficient and practical tools for frequency domain analysis and fatigue calculations have been promised for 30 years and at last, today, they are a reality.”

HyperSizer is an aerospace-centric software suite that is used to quantify all critical failure modes, reduce structural weight, and sequence composite laminates for fabrication to avoid unexpected design problems and weight growth as the design matures.

HyperSizer is used by importing a finite element model (FEM) directly into the software along with the corresponding FEA-computed loads. HyperSizer then analyzes using non-FEA failure methods to quantify safety factors and eliminate negative margins of safety for thousands of mechanical and thermal load sets. It then optimizes to quickly determine the lightest weight combination of material systems, cross-sectional dimensions, and ply layups for all panels and beams in the structure and automatically iterate with FEA for load convergence.

By using HyperSizer companies will be able to reduce structural weight (by more than 20%), increase productivity, reduce design cycle time and certify structures faster.

Geoff Haines, managing director at DTE, said: “Our heritage in the FEA space and our existing relationships with Dassault Systèmes and MSC Software lends itself to selling CAEfatigue VIBRATION and HyperSizer. The commercial benefits of both are easy to understand and NAFEMS is a great platform to launch these solutions to the engineering analysis community.”

The 2014 NAFEMS Conference, a two-day event, will explore the extent to which Computer Aided Engineering (CAE) has been realized and what more there is to be achieved. It will focus on existing best practices as well as state-of-the-art FEA, CFD and associated technologies.

Desktop Engineering is an accredited business partner with Dassault Systèmes and MSC Software, supporting the industry standards of CATIA, DELMIA, ENOVIA, Nastran, Patran, Marc, and Adams.
