Jovan Trajkovski, PhD is an Assistant professor at the Faculty of Mechanical Engineering, University of Ljubljana and a member of IAPS (International Association of Protective Structures). He has more than 15 years’ experience in numerical modelling of blast response of structures using practically all the available methods. His PhD research was conducted on design optimization of centrally and eccentrically blast loaded plates with different geometries. His research work is published in numerous scientific papers and conferences mainly in the field of numerical evaluation of blast response analysis of plate structures, Light Armoured Vehicles, human injury assessment, design of blast-resistant components and infrastructure.
Short abstract of the speech
Numerical examination of blast loaded structures is of great importance in design evaluation of military equipment, public structures and other governmental buildings that can be potentially exposed to blast loading. Analytical solutions are limited to simple structural geometries, experiments are expensive and often impossible to perform which makes the numerical analysis the most powerful tool for structural evaluation of blast loaded structures. However, precise numerical modeling of blast wave development and blast loading of structures is one of the most complex problems in computational dynamics. The methods that are available for numerical modeling like Multi-Material Arbitrary-Language-Euler (MM-ALE), Smooth-Particle-Hydrodynamics (SPH) or Corpuscular Particle Method (CPM) are quite demanding for use and have their own advantages and disadvantages depending on the structural geometry and its relative position with regard to the blast wave source location. The speech will cover the most valuable aspects for building quick and cost-effective numerical models that can be easily applied for response evaluation of blast loaded structures.
