Abstrakt
In the present paper the following problems are addressed: 1) bending of a plate at coating growth or removal; 2) bending of a plate with coating at temperature variation troughout thickness; 3) bending of a plate with a coating loaded by concentrated forces; 4) thermoelastic modelling of the bending of a coated straigth strip substrate by using thermoelastic bimetallic strips. It was found that at coating growth or removal the composite substrate- coating with a relative width of b/l= 0.05-0.5 bends like a plate that is non-homogeneous troughout thickness and is subjected to uniformly distributed edge moments (pure bending). However, in the case of a concentrated moment, the same substrate-coating behaves like a nonhomogeneous beam.
