Tensile Crack Tip Fields in Elastic-ideally Plastic Crystals
Crack tip stress and deformation fields are analyzed for tensile-loaded ideally plastic crystals. The specific cases of (0 1 O) cracks growing in the [1 0 1] direction, and (1 0 1) cracks in the [0, 1, O] direction, are considered for both fcc and bcc crystals which flow according to the critical resolved shear stress criterion. Stationary and quasistatically growing crack fields are considered...
متن کاملElastic-plastic Deformation at Finite Strains
In some circumstances, elastic-plastic deformation occurs in which both components of strain are finite. Such situations fall outside the scope of classical plasticity theory which assumes either infinitesimal strains or plastic-rigid theory for large strains. The present theory modifies the kinematics to include finite elastic and plastic strain components. For situations requiring this genera...
متن کاملRICE A Path Independent Integral and the Approximate Analysis of Strain Concentration by Notches and Cracks
A line integral is exhibited which has the same value for all paths surrounding the tip of a notch in the two-dimensional strain field of an elastic or deformation-type elastic-plastic material. Appropriate integration path' choices serye bOlh to relate Ihe integral to the near tip deformatiot~s and, in many cases. to permit its direct e:tlalutllion. This (l.t'eraged measure of the near tip fie...
متن کاملElasto-plastic stress and strain behaviour at notch roots under monotonic and cyclic loadings
Notch deformation behaviour under monotonic and cyclic loading conditions was investigated using circumferentially notched round bar and double-notched flat plate geometries, each with two different notch concentration factors. Notch strains for the double-notched plate geometry were measured with the use of miniature strain gauges bonded to specimens made of a vanadium-based microalloyed steel...
متن کاملNumerical modelling of elastic-plastic deformation at crack tips in composite material under stress wave loading
The paper deals with the elastic-plastic wave propagations in an anisotropic material subjected to impact loading with emphasis on an ideal fibre-reinforced cubic material under two-dimensional plane strain condition. The system of partial differential equations is hyperbolic. Therefore a characteristic-based difference method is proposed to calculate the formation of the plastic zone at the cr...
