Libido

Local and global instability in fracture mechanics, crack growth and/or fast crack propagation, depending on material strength, ductility and toughness as well as on structural size-scale. Initially uncracked elements of brittle material may reach their maximum loading capacity with a sudden crack formation and uncontrollable crack propagation, wher

含鐵

A strain-rate dependent model for crack growth,uation which is assumed to depend on the material while the interaction of material with local stress and/or strain is neglected. The form of the constitutive equation is preassumed and is taken to be the same for all material elements of the continuum. Such an approach, however, should be seriously

Failure of a plate containing a partially bonded rigid fiber inclusion,ed mechanical and physical properties in combination with light-weight components. For this reason, they are now being widely used for aerospace and other applications where high strengths and stiffness-to-weight ratios are required. These materials are usually made of glass or boron, graphite or ot

演講

Strain energy density criterion applied to mixed-mode cracking dominated by in-plane shear, another should be describable by a single failure criterion. The time dependent crack growth relation may be stated in the general form . The crack size ., load parameter . and fracture resistance parameter . that is characteristic of the material can, in general, be time dependent.

Conclave

Group-averaging methods for generating constitutive equations,try properties. This requires that we find the canonical form of scalar-valued functions .(.,…) and tensor-valued functions . (.,…) which are invariant under the group of transformations {.{ defining the material symmetry. Solution of these problems frequently requires a substantial computational ef
