CONTINUUM/DISCRETE MODELLING OF DAMAGE AND FAILURE IN STRUCTURES AND SUBSEQUENT REPAIR STRATEGIES

摘要：

This paper discusses computational approaches employed in the modelling of damage caused by blast, impact and natural loading and considers the development of retrofitting or mitigation strategies. An essential prerequisite to the design of retrofitting techniques is knowledge of the stress, displacement and fracture states in the damaged structure. Prediction of the damage induced in solids and structures due to blast and impact loading is therefore discussed and repair strategies based on anchor stitching methods are illustrated. Applications from several relevant areas are presented to illustrate the capabilities of continuum/discrete computational procedures.
