For two-dimensional plane stress problem, the relationship between macroscopic damage variable and the averaged microcrack density parameter for concrete under biaxial tension stress is presented based on the equivalence hypothesis of energy dissipation.
Some progress is reviewed related to energy dissipation in the field of rock mechanics,and a macro-meso-micro system based on damage evolution and energy dissipation is suggested,which contributes to solve more engineering problems exactly.
This paper deals with the energy dissipation rate for side-grooved,deep notch,and three-point-bend test pieces of HY-130 steel with samethickness but different width.
The damping ratio is studied by the complex mode method, the forcing decoupling method, and the equivalent damping method based on deformation energy. Some rules for choosing the design method and the calculation accuracy of the structure are obtained in this paper, it is of great significance for energy dissipation devices.
A method based on the energy dissipation mechanism of an Independent Oscillator model is used to calculate the frictional force and the friction coefficient of interfacial friction.
