A 4x4 meter [45/-45]s balanced symmetric layup (note 4 plies) is used in a space applications where the change in temperature is AT=-100C. Once on orbit at this temperature, the sample experiences 400 N along the y-axis (all other loads and moments are zero). The lamina has the following material properties and the thickness of each ply is 100 microns. 45 degree angle 45 40 35 10 Pa []=40 50 35 35 35 40 -45 degree angle 40 -35] 50 -35 -35 -35 40 45 [0] = 40 10 Pa 10 [a]= 10 x106/C -25 [a] = 10x10 /C - 10 x10 25 a) What are the effective thermal loads (NT, M) and mechanical loads (N, M)? b) What are the midplane strains and curvatures due to this loading? c) What are the maximum stresses in the x-y coordinate system of the third ply?
