โœฆ Synopsis

Creep Energy Dissipation (CED) rate due to crack-tip creep zone and load-line deflection rate are calculated under small-scale creep conditions for Compact Tension (CT) specimens of four different widths. It is observed that CED rate has a unique parabolic relation with the crack-tip stress intensity factor, K and thus it depends on the specimen width. Also, it is shown that the ratio of load-line deflection rate due to creep deformation to elastic load-line deflection is uniquely related to K.

Creep energy dissipation (CED) due to crack tip creep zone is determined under steady state conditions for centre cracked thin specimen of 1.25CrOSMo steel, with different widths and crack length to width ratios. The creep energy rate increases when the increment in crack length Au increases and the

Linear elastic fracture mechanics predicts a characteristic distribution of tensile stress ahead of a crack tip in a body subjected to a remote tensile stress normal to the crack faces. The relaxation of this stress distribution, arising from steady state creep behatiour, is here examined. An Etppra

A method for the crack tip analysis of a tensile loaded crack (mode I) due to yielding of the material is developed. The stress/strain distribution within the plastic zone, as well as size of the plastic zone are presented. The development is based on the energy interpretation of the strain hardenin
