Method to Analyze the Effect of the Shock-Wave Loading on Building Elements

During designing of some modern industrial and civil buildings it is necessary to consider influence of the intensive impact-wave loadings. The strain rate deformation of building and structural elements takes place both in the elastic and in plastic stage. In such tasks, it is necessary take into account presence of finite deformations as well as dynamic properties of materials. The calculation of above nonlinear task, including dynamic stress-strain states in elements, is carried out by the method of finite differences. Thus, an adaptive net is used on space and temporal to co-ordinates. Accuracy of numerical simulation is verify on every step of calculation, and if necessary change of step is involved.
