On crack band model in finite element analysis of concrete fracture in engineering practice
Original language description
When finite element nonlinear analysis is applied to address the typical engineering problems such as ultimate load carrying capacity or serviceability limits such as deflections or crack width, a special care should be taken for the proper definition of the crack band namely in the presence of reinforcement. The definition of crack band in tension should take into account the reinforcement spacing as well as finite element size. The crack band size should be also limited from below depending on the minimal possible spacing of micro-cracks. In compression failure an analogical concept to the crack band method can be introduced, but again the compressive band size should be limited from below depending on the characteristic dimensions of the analyzed structure. The paper proposes three localization limiters for practical applications of nonlinear finite element model using the smeared crack approach and crack band method both for tension and compression. The application of these localization limiters is demonstrated and verified on several problems ranging from shear failure, bending behavior and compressive failure. It is demonstrated that the simple application of these limiters can increase the accuracy of finite element analysis even if very small or very large finite element sizes are used, which is often necessity in practice or research and development.
