Uniaxial and triaxial behavior of high strength concrete with and without steel fibers
… The experimental study mainly focuses on the octahedral shear stress strain relationship of those two types of concrete, which is adopted as the basis to develop a new incremental constitutive model. Emphasis is also put on the investigation of the variation of tangent Poisson's ratio under …

Fracture analysis of an axi-symmetrical solid
… in the region of highest triaxiality of the stress σ<sub>ii</sub> under the ultimate load, rather than at the root of the notch. Thus the maximum value of σ<sub>ii</sub> at ultimate load becomes the assumed criterion for the first phase of the fracture; i.e., the brittle fracture. The crack …
