An instantaneous laser pulse of 10 MJ/m? is imposed on a slab of stainless steel having properties
of p= 7800 kg/m?
„C= 460 J/kg. °C, and a = 0.44 x 10-5 m2/s. The slab is initially at a uniform
temperature of 40 °C. Estimate the temperature at the surface and at a depth of 2.0 mm after a time
of 2 s.
