Investigating the stability response of axially compressed structural elements

Investigating the stability response of axially compressed structural elements

This is a past event

Dr Voellmecke, from Berlin Technical University, is an expert in the field of fracture and failure mechanics, numerical mathematics and computer simulations. Her research interests are in geometrically nonlinear analysis of stability phenomena (analytical and numerical), local and global failure analysis, mode interaction, composite structures and materials, sandwich structures. She will be visiting the School of Engineering, in particular the Centre for Micro- and Nanomechanics, from March 19 to March 22.

Structural elements under compression can be found in (almost) any engineering application. These components are usually required to be designed to lightweight principles by reducing their overall weight whilst achieving an optimum in stiffness. Owing to their advantageous material properties fibre-reinforced composites or sandwich structures are often used to transfer the load efficiently since material is assigned where needed most. However, different (failure) modes may occur under compression potentially compromising the buckling and postbuckling responses of the components.

Investigating the underlying mechanisms may be undertaken using e.g. analytical and numerical techniques allowing for geometric nonlinearities. Different modelling approaches are discussed to simulate and assess the phenomenological behaviour of compressed structural elements. Results from numerical and analytical investigations are briefly presented. An overview of the work currently being undertaken by the author will be given whilst future research developments and interests are highlighted.
