Finite element analysis of concrete: Discrete cracking, Smeared crack and XFEM for concrete fracture and damage Simulation
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
Modelling the damage and crack initiation and propagation until structural failure can be carried out by realistically modelling the geometry and the material behavior of concrete, and 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 such as ANSYS, ABAQUS, NASTRAN, LS-Dyna and MSC Marc by using advanced method for simulation such concrete complicated and nonlinear behavior with discrete cracking, smeared crack and XFEM for concrete fracture and damage Simulation.
In materials science, fracture toughness refers to the ability of a material containing a crack to resist fracture. Specifically, fracture toughness testing characterizes resistance to fracture in a neutral environment with a sharp crack, and is one of the most important properties of any material for virtually all design applications. Finite Element (FEA) Fracture simulation is used in design and fabrication to understand and prevent brittle fracture in concrete structures. It can also be used to determine the useful life of concrete structures under different conditions, including fatigue, corrosion and elevated temperatures.
