| description | Composite materials consist of a matrix and fibers, and their failure modes differ significantly from those of isotropic materials. In undamaged composite materials, under increasing loads, matrix damage typically occurs first. At this stage, the damaged area experiences a stiffness reduction, redistributing stress until failure occurs elsewhere. As matrix damage progresses, debonding between fibers and the matrix begins, leading to delamination failure. With further load increase, the fibers eventually fracture. Finite element simulation with stiffness degradation methods can be employed to study composite material damage. This involves gradually degrading damaged elements, ultimately revealing the final failure mechanism of the composite material. Advances in finite element software now allow for precise engineering simulations, widely applied in the field. Consequently, this method can be used to simulate and analyze the failure of composite material flywheel rotors, identifying the factors contributing to their failure. This study uses progressive damage theory to simulate the failure process, establishing rational failure criteria for composite materials and utilizing a finite element stiffness degradation model. Greater interference fit results in higher compressive stress and initial stress, making the compressive stress and initial stress distribution of composite material flywheel rotors dependent on the interference fit. The study also analyzes the critical speeds of flywheels with single-ring and multiring rotors under different interference fits, revealing the influence of interference fit on the maximum speed of the flywheel. |
