On point cloud failure criterion predictions
Journal of Composite MaterialsA new failure criterion has been developed to improve modeling of orthotropic structural composites subjected to quasi-static and impact loadings. Rather than using an analytical expression that traditionally has been employed to predict failure, a point cloud failure surface is constructed in the stress/strain space using a combination of virtual and

Dual Failure Criterion for Plain Concrete
Journal of the Engineering Mechanics Division, 1974Considering plain concrete as an isotropic homogeneous continuum, a criterion has been proposed to govern the failure of this material. According to this dual fracture-yield criterion, two modes of failure are possible, i.e., the material element may fail either in shear or in tension depending upon the corresponding strain (stress) state.

Deformation criterion of salt rock failure
Journal of Mining Science, 2016The author offers a new deformation criterion for the compressive strength of salt rock specimens. The limiting principal strain is a function of stress parameter in the form of a ratio of hydrostatic pressure and stress intensity. The safety factor based on the deformation criterion is defined.
