Abstract | The non-linear response for both static and dynamics is presented using the concept of Continuum Damage Mechanics. The analysis is performed using the finite element technique and appropriate material nonlinearity damage models. Modify Newton-Raphson approach has been used at each loading step. Damage evolution based on tensile principal strain is adopted to calculate the accumulated damage. The damage model is shown to be efficient and consistent of both damage growth and damage propagation. An 8-node solid element using concept of damage mechanics is developed in XFINAS program the nonlinear response of concrete in tension and perfect plasticity in compression are considered. A series of numerical examples in static analyzed by the XFINAS program based on damage mechanics concept are represented and compared with the experimental results to demonstrate the validity and applicability of an element. Finally two types of concrete arch bridges subjected to air blast loading has been analyzed by XFINAS and the results are compared with the solution from non-linear dynamics with elastic materials. |
