Vegard Aune
Bakgrunn og aktiviteter
Dr. Aune wrote his PhD degree in relation to the two Centre’s for Research-based Innovation SFI SIMLab and SFI CASA. The PhD thesis is titled "Behaviour and Modelling of Flexible Structures subjected to Blast Loading". He has given several lectures on the behaviour, modelling and simulation of blast-loaded structures to the industrial partners in the SFI centres. He has also been involved in the Industrial Implementation group in SFI CASA since October 2016. The objective of this group is to monitor new developments in SFI CASA and to assist in the implementation of these at the industrial partners. An essential part of the Industrial Implementation group is therefore to evaluate the needs each industrial partner has for support from NTNU in the implementation, and to provide guidelines with respect to modelling and design.
The present research of Dr. Aune is primarily related to the behaviour, modelling and simulation of aluminium and steel structures subjected to blast loading. This includes the development of test facilities for controlled, repeatable testing of components and structures in blast environments. The overall objective of his research is to evaluate the capabilities of current computational methods in predicting the dynamic response of the tested components and structures. He has conducted material testing of aluminium and steel; structural impact testing of aluminium, steel, glass and concrete; and performed non-linear finite element simulations in several commercial computational software. Special focus is placed on the behaviour and modelling of metallic materials under these extreme loading situations. This involves the development, implementation and use of material models related to steel and aluminium, as well as identification of the necessary material parameters.
