Simulating Composite Materials and Structures

Seminar:

Simulating Composite
Materials and Structures


17 – 18 November 2015
Stockholm, Sweden

Invitation

Composite structures or components are increasingly used as primary load.The successful application of Finite Element methods for the design of components and structures which are made of modern materials strongly depends on the ability of the designer to choose the correct lay up, fiber orientation etc. The development of numerical methods and faster computers, better design criteria etc. makes it much more economically efficient than experimental testing - although that experimental test in some extent is still needed.

Embedded in the quest to computerize composite designs is also a challenge of capturing global as well as local effects. In fact, understanding of the micro scale failure scenarios, i.e. brittle and ductile fracture, progressive cracking, debonding, delamination, etc, is a prerequisite to enable building of macro scale modeling techniques which can readily be used in product development. It is anticipated that an increased use of these materials, together with advanced Finite Element analysis (FEA) methods to predict the limits of structural integrity more precisely, lies ahead.carrying structures in nearly all fields of our society, taking advantage of the increased structural strength and stiffness to weight ratios, corrosion resistance, or more innovative design capability that composites bring.

The nature of the composite used can range from cheap and freely available glass fiber reinforced systems to exotic and specifically tailored carbon, aramid or even metal/matrix systems, with many forms of manufacturing process available.

The design may include thick composite sections with large numbers of plies, there may be regions of significant ply drop off, sandwich construction and also bonded joints. In this case the strength prediction may become very difficult and can often only be solved with the incorporation of advanced experimental tests.

The seminar is intended as a forum for experts in the area of prediction and modeling of composite structures by using finite element analysis (FEA). The event is accompanied by an exhibition of engineering software, computer systems, and related consultancy services. A comprehensive review of the current state-of-the-art and trends as well as of future challenges will thus be accessible to participants.

We are looking forward to meeting you in Stockholm.
