FEA Simplifies the Design of Complex Composite Structures

When I first got introduced to composites as a student (many years ago!), I remember having felt amazed at how powerful yet complex materials they are. In a recent interview published in Composites in Manufacturing, my colleague Marc Wintermantel expressed the challenge of designing composites products very nicely: “When a designer uses simulation software to define composite part points in space they have a tremendous amount of additional design options and parameters to deal with.[…] These options are so large that you need to depend on optimized simulation tools because the computations go way beyond most people’s abilities to perform these tasks by hand”. And indeed, how can an engineer figure out what the optimum stackup is for a given applications with so many possibilities for fabrics thicknesses, orientations or location choices? Steel or aluminum are much easier to deal with! Continue reading

Submodeling of Composites Laminate Structures Using ANSYS Composite Prepost 15.0

Delamination or interlaminar fractures of composite laminates are generally caused by high interlaminar stresses that arise due to mismatch in elastic properties between plies and at free edge. Therefore, understanding the behavior of these stresses is of critical importance in the assessment of structural integrity of composite materials and structures. Continue reading

ANSYS Acquires EVEN: Adding Layers to ANSYS Mechanical

Guten Tag ANSYS Schweiz – Bonjour ANSYS Suisse – Buongiorno ANSYS Svizzera – Bun di ANSYS Svizra

Today we announced with great pleasure the addition of EVEN – Evolutionary Engineering AG (EVEN) to the ANSYS family. EVEN was founded in 2004 in Zürich by Marc Wintermantel, Oliver König and Nino Zehnder with the goal of making optimization and composites post-processing software.

compositesComposites are created by blending two or more materials that possess different properties. Because they combine light weight, high strength and outstanding flexibility, composites have become standard materials for manufacturing in a range of industries. For this reason, composites will continue to be extremely popular with leading manufacturers around the world.

For example, we have seen growth in the use of composites in such industries as jet engines, wind turbines and automotive, among many others. We expect to see even more applications in which composites play a key role in the future, and ANSYS will be ready to supply the tools needed to get this critical work done. Continue reading
