John A. Parrish M.D.,R. Rox Anderson,Frederick Urbach M.D.,Donald Pitts O.D., Ph.D.ircumstances can be predicted and prevented by elastic or viscoelastic stress, strain and deflection analysis as described in earlier chapters. The focus in this chapter will be on excessive deformation due to time-dependent yielding and/or progressive damage accumulation leading to rupture.

However, the nano-sized Bi.O.–PVA composite with starch offered better particle size effect for X-ray shielding ability than its micro-sized counterpart compared to the Bi.O.–PVA composites without starch.
