Calculation of structural collapse lever mechanisms taking into account the elastoplasticity
In this paper a calculation of the destruction of the finite-element models of structural linkages. In statically indeterminate structures exhaustion of the bearing capacity of an element does not cause the destruction of the whole system, because the remaining elements form an unchangingsystem. Limit state of the assembly will be achieved only when the carrying capacity is depleted as many elements as required to ensure the geometric immutability. This idea is taken as the basis of calculation and is shown by the example of the excavator bucket. Elastoplasticty more fully utilizes the resources of structural strength and leads to savings in material
