Unformatted text preview: Two diﬀerent scenarios are to be considered: (a) d << L, d << w and the lateral walls of the block–those determined by d the equation of the planes x 2 = 2 –are unrestrained in the x 2 direction, ± i.e. the plate can expand out of its plane. (b) The lateral walls of the block are not allowed to expand out of its plane. w δ L x x 1 3 d x x 3 2 d x x 3 2 (a) (b) 2. Problem 4.4 from textbook 3. Problem 4.6 from textbook but change the complementary strain energy to the strain energy 4. Problem 4.7 from textbook 5. Obtain a numerical value for the elastic energy stored in the block of problem 1 when L = 10 cm, w = 10 cm, d = 1 mm, E = 70 GP a, ν = 0 . 3 , δ = 2 mm . Consider both cases of plane strain and plane stress. 3...
