  • Fracture of modified urethane - methacrylate resins 
    Zhang, Xiangcheng (1993-03)
    Fracture and toughening mechanisms in rubber modified and hybridized urethane-methacrylate resins have been investigated. Fracture mechanisms are defect-dominated in the unmodified resin. The relationships between defect ...
  • A fracture of rubber in a state of finite torsional shear 
    Hall, M. M.; Sollars, A. R. (College of Aeronautics, 1969-01)
    A solid rubber cylinder with metal end plates fractured in the rubber when a torsional deformation was applied 'which corresponded to a shear angle of 56° on the cylinder surface. The height of the cylinder was ...
