Material data during crack growth simulation
Add to calB004 Engineering Central, Swansea University Bay Campus
Join us on Tuesday 14th March in B004 Engineering Central, Swansea University Bay Campus to learn about Material data during crack growth simulation by Cris Timbrell from Zentech.
About the company: Zentech specialises in applying advanced engineering techniques to engineering problems. These include detailed simulation of 3D non-planar crack growth, assessment of structural integrity, forensic analyses, design of offshore flexible riser systems and controlled floatout/sinking of large diameter HDPE outfall pipes.
Talk summary: The finite element method, coupled with remeshing techniques, permits a variety of different types of crack simulation. The usual range of material data required for finite element analysis must be supplemented for fatigue crack growth prediction, for example, by data in the form of a crack growth law. The approach for crack growth prediction will be outlined before considering some issues related more directly to the use of material data as part of the process. Areas where material issues can complicate matters include high temperature effects and modelling crack growth in welds, in additive manufactured parts and in bonded repairs.
