ABSTRACT
Abstract The Bochum Method for numerical simulation of damage process in material structure has been developed since 1984 to that state of practicability which is needed for studying interface problems sufficiently. The investigations were made by two types of mechanical models: A simple plain model of a body with one single particle of aggregate in a binder and a 3-D-model of concrete. Comparing the results of tensile and compression tests it can be shown how sensitive a material as concrete alters its properties due to interface behaviour. Keywords: Numerical Simulation, Modelling of material structure. Interface dependent properties
1 Introduction
In experimental investgation particular material properties depending on material structure - e.g. stress strain curve, strength, elongation, modulus of elasticity etc. - can be measured. The damage process itself consisting of microcrack formation and microcrack accumulation due to loading up to material failure by macrocrack opening can not be observed in experiments easily. The Bochum Method of Numerical Simulation allows to study damage processes on a mechanical model of material structure. The stress strain curves or other proporties calculated by numerical simulation can be compared with properties measured in experimental investigations.
