- Abstract
- The mechanical model of fiber composite gives an idea of background hypotheses used to derivation of defining relationships for materials. It qualitatively describes straining and destructions observed during experiments. In this work it is offered to use a framing as model. For this construction we received linear dependences between power factors and movements, we built the dependence schedules between mechanical characteristics and angle, which is used as reinforcement angle analog. The analysis of behavior of a construction outside of elasticity was carried out. Analytical dependences of external loadings of the first destruction and loadings at which the construction turns into the mechanism were deduced. Typical diagrams of deformation which are compared to known experimental data are drawn.
