【 摘 要 】

One of the most demonstrative examples of fibrous composites application in the vehicle power structures is a spring. Fiberglass springs are not uncommon, the existing analytical design methods allow calculating its overall dimensions under the conditions of strength and stiffness, but the behavior of leaf springs with defects under load is the point of interest. At the same time, the enormously approach is extremely complicated, but modern calculation methods allow to model defects, their growth and the process of destruction, taking into account the specifics of fibrous composites. In the paper considered the process of modeling the progressive destruction of fiber reinforcement plastic (FRP) leaf spring. The here presented calculation procedure is for one-leaf spring. The features of the calculation using MSC Patran are described.
