Thermoelastoplastic Bending of Complexly Reinforced Plates

A problem on the transverse-longitudinal bending of reinforced plates of variable thickness under a thermal-force loading is formulated. A qualitative analysis of the problem is carried out, and a way of its linearization is indicated. Calculations of isotropic and metal composite plates subjected to the transverse or transverse-longitudinal bending showed that their bearing capacity in the elastoplastic bending is a number of times (occasionally, by an order of magnitude) greater than in the elastic bending. The heating of the plates sharply decreases their resistance to the bending in the case of elasticity and affects it only slightly in the case of elastoplasticity. In the elastoplastic bending, the bearing capacity of the metal composite plate a number of times exceeds that of isotropic plates made of conventional structural metal alloys. __________ Translated from Mekhanika Kompozitnykh Materialov, Vol. 41, No. 6, pp. 715–742, November–December, 2005.
