Plot the strain and stress distribution (?x and σy) through the thickness of the bimetallic analyzed in Exercise 6.23.
Compute the curvature of the bimetallic in Exercise 6.3 when it is subjected to a change of temperature ?T = 10 ?C.
Exercise 6.3
Compute the extensional [A], coupling [B], and bending stiffness [D] matrices of a bimetallic (copper and aluminum) strip with each lamina 2 mm thick. For aluminum E = 71 GP a, α = 23(10-6 )/ ?C. For copper E = 119 GP a, α = 17(10-6 )/ ?C. Assume the Poisson's ratio is 0.3 for both materials.
