The Specific Energy Modal Components of the Impact Dynamic Loads in a Solid

The article presents the analysis results of the energy density formation regularities for the linear, tangentially and torsion dynamic deformations in solids. The article describes that the correct calculation of these deformations specific energy is essential to estimate their contribution to the reduction in the structural materials strength. It is shown that the Clapeyron formula canonical expression for energy density of the static deformations in the solid is not valid in the case of dynamic deformations. The article presents a refined expression for the specific energy calculating formula, which can be used to calculate the rate of structures depreciation. This formula takes into account all the components of the dynamic deformations tensor which are present in solid multimode dynamic loads. Such multimode loads are affectedat impacts on structures.
