Baker (University of Illinois) has found that for "resolved shear stress" above 100 lb./sq. in. lead crystals exhibit "creep" and are inelastic. By using the bending beam method it is possible to test for elasticity below Baker's limit. It is then found that lead single crystals, specimens containing several large crystals and even multi-crystal specimens have a definite Hooke's Law region of elastic behavior with no creep.
