1. Determine the central displacement - time history of the square clamped aluminium plate of side a=200 mm and the thickness of h=2 mm for 20 ms. The plate is subjected to the following time-dependent, transverse surface load: -at/t, p(x, y,t) = P.(1-t/to)e where pm=100 kPa, tp=0.0018 s, a=0.35. The material properties are E=70 GPa and v=0.3.
