Comment:reduction of t2 in comparison with a plate of zero initial values t20 is again

almost independent of Z0 , and depends mostly on :0. An average reduction is of about

10%.

Comment:It is seen that higher the initial value of :0 higher is the value of global

damage accumulated in time t1 , but the value of accumulated global parameter over its
