Fracture criterion for notched thin composite laminates
37th Structure, Structural Dynamics and Materials Conference, 1996Fracture behavior of fiber-dominated center-notched AS4/3501-6 graphite-epoxy laminates is investigated in this study. Nine laminate configurations are studied to examine flaw size effects, crack tip damage mechanisms, and failure modes under uniaxial tensile loading.

Criterion for Fracture of Plain Concrete
1983Concrete is a composite material consisting of aggregate inclusion and cement-paste matrix and the cracks which result from the interface between inclusion and matrix play an important role for the deformation and failure of plain concrete [1]. On the base of the observations of the physical and mechanical properties at the aggregate-paste interface ...

A Fracture Criterion for Piezoelectric Material
2010A fracture criterion for piezoelectric ceramics is proposed which is based upon the energy release rate and two phase angles determined from the ratio between the intensity factors. It is assumed that the crack plane is at an angle to the poling direction within a symmetry plane of the body.

Fracture Criterion and the Life of Materials during Brittle Fracture
Russian Metallurgy (Metally), 2020A structural–statistical kinetic model is developed to describe the brittle fracture of materials at low stresses. Expressions are derived for the average life of a material at low stresses, and a kinetic meaning of the brittle fracture criterion is formulated.

BEHAVIOUR AND CRITERION OF QUASI-BRITTLE FRACTURE OF MATELS
Engineering Fracture Mechanics, 1991Abstract In this investigation complex stress state is related to the stress state in uniaxial tension by use of the concept of effective stress from the elastoplastic theory. Considering that in metals the crack growth is usually accompanied by locally plastic deformation in front of the crack tip, and the extension of a crack will always pass ...

A Generalized von Mises Criterion for Yield and Fracture
Journal of Applied Mechanics, 1980Yield and fracture criteria for real materials are to a varying degree affected by a state of hydrostatic stress. Some materials, after certain deformation history, exhibit different yield point when the direction of the stress is reversed, a behavior known as the Bauschinger effect.

Experimental Det.-Criterion of Fracture
1993For plane conditions the maximum shear stress τm is related to the Cartesian components of stress by [53, 279, 280]: $$ {(2{\tau _{m}})^{2}} = {({\sigma _{{xx}}} + {\sigma _{{yy}}})^{2}} - 4{\text{Det}}.({\sigma _{{{i_{j}}}}}) $$ (789) Where Det.(σij) = σxx σyy-τ2xy, and the stress-optic law relates the isochromatic fringe orderN to τm by the
