Invitation

During the past decades the use of FE methods has become a common practice in the design of industrial products. For the vast majority of metallic structures the material characterization in FE analysis assumes a linear elastic isotropic behavior. The ever increasing use of non-metallic materials in most industrial products has caused the need for more advanced material modeling. The wide spectrum of industrial materials ranges from linear elastic metals through visco-elastic polymers, incompressible elastomers, highly compressible porous materials like foams to anisotropic reinforced plastic or metal matrix composites. In addition there is an increasing demand to capture the true behaviour of traditional but complex materials such as reinforced concrete and soils.

Apart from the fact that the constitutive behavior of such complex materials requires the availability of material parameters that characterize the behavior under all possible load spectra, the dependency on temperature, time and/or viscous effects makes the determination of material parameters quite challenging.

The successful application of FE 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 constitutive model, to apply the correct material parameters and to understand the underlying numerical procedures of the FE programs in which the constitutive models are implemented.

One of the main purposes of detailed FE analyses as part of a design process is to determine the safety margin that the relevant component or structure exhibits before failure occurs.

In most cases the detailed information about maximum principal stresses in the structure is matched with material data on tensile rupture or shear failure in order to determine the maximum load carrying capacity and the resulting safety margin. Such simplistic approaches have only limited applicability in case of complex load combinations and for materials that exhibit complex material failure phenomena due to their inherent complex behavior, e. g. for laminated reinforced composites. It is anticipated that the increased use of such advanced materials combined with the necessity to calculate the structural integrity more precisely, will result in an increasing amount of advanced FE analysis to simulate failure phenomena like progressive cracking, debonding, delamination , brittle and ductile fracture, etc.

This seminar will focus on the practical aspects of the analysis of modern materials in the design process including the ability to simulate failure phenomena. The practical use will be demonstrated through examples of industrial applications. In addition the seminar will give an insight in the current state of the art of the development in the area of failure analyses.
