The Speed of Ductile-Crack Propagation and the Dynamics of Flow in Metals,sis based on a dynamic solution for the Dugdale crack model and employing descriptions of 1) the strains within the plastic zone, 2) the rate dependence of the flow stress, and 3) a simple criterion for ductile fracture is developed. The calculations are found to compare favorably with observed crac

Constitutive Relationships from Impact Studies,urve for high purity aluminum and copper single crystals could be represented as a 1/4 power law. This particular deformation law as found to be predictable using the stress and strain ratios of the aggregate theory of Taylor. These predictions were made on the basis of the deformation of polycrysta

Prediction of Elastic-Plastic Wave Profiles in Aluminum 1060-0 Under Uniaxial Strain Loading,e of two flat plates has a two-wave structure as shown in Fig. 1. The elastic wave propagates at velocity . with intensity . where . is the yield stress of the material in a uniaxial stress test, λ and μ are Lame’s constants, and p is the material density. This is followed by the higher intensity pl

The Relationship Between the Constitutive Equation and One-Dimensional Wave Propagation,erial with a yield stress significantly lower than the applied stress. Various constitutive relationships are assigned to the bar material. Wave front profiles, in terms of the axial strain, are computed for each constitutive relationship, and for different values of the constants that appear in the
