[Strain] The rectangular plate deforms into the dashed shape shown. (a) Determine the average normal strain along the side CD.

(b) Estimate ?y at point A.

(c) Estimate ?xy at point A.

(d) Estimate ?xy at point B.

Solution

(a) Average normal strain along CD = 0.5 x (0.02/100 + 0.1/100) = 6 x 10^-4.

(b) _y at point A = 0.01/50 = 2 x 10^-4.

(c) _xy at point A = 0.5 x (0.02/50 + 0.01/100) = 2.5 x 10^-4.

(d) _xy at point B = 0.5 x (0.05/50 + 0.1/100) = 1 x 10^-3.
