The Basic Soltion he demerara es Problems Chapter f the basic solution of he temperature Stress Problems When the temperature of a elastic body changes, its volume will expand or contract. If the expansion or contraction cant happen freely due to the external restrictions or internal deformation compatibility demands, additional stresses will be produced in the structure. These stresses produced by temperature change are called thermal stresses, or temperature stresses Neglecting the effects of the temperature change on the material performance, to solve the temperature stresses, we need two aspects of calculation: (1) Solve the temperature field of the elastic body by the initial conditions and boundary conditions, according to heat conduction equations And the difference between the former temperature field and the later temperature field is the temperature change of the elastic body. (2) Solve the temperature stresses of the elastic body according to the basic equations of the elastic mechanics. This chapter will present these two aspects of calculation simply 5
