Finite element analysis of Reinforced Concrete: Fracture & Damage

FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization

Modelling the damage initiation and propagation until structural failure can be carried out by realistically modelling the geometry and the material behavior of concrete, and individual reinforcement, individually and by defining their complete interconnection. Furthermore, the wide range of advanced special purpose finite element user defined and general-purpose software analysis functionality allows modelling of the structure from construction, through service life to failure. Design and assessment of Service and Ultimate Limit States up to integral failure analysis can be carried out in single FEA software by using advanced method for simulation such complicated and nonlinear material and structure.
