Query: Elastic modulus and yield strength of semicrystalline polymers with bond
  disorder are higher than in atomic crystals   We perform thorough molecular-dynamics simulations to compare elasticity and
yielding of atomic crystals and model semicrystalline polymers, the latter
characterized by very similar positional ordering with respect to atomic
crystals and considerable bond disorder. We find that the elastic modulus, the
shear yield strength and the critical yield strain of semicrystalline polymers
are higher than (modulus and yield strength), or comparable to (critical
strain), the corresponding ones of atomic crystals. The findings suggest that
the bond disorder suppresses dislocation-mediated plasticity in polymeric
solids with positional order.
