FEM Simulation of Plastic Zone in Front of the Fatigue Crack with Shear Lips
In this paper, numerical simulation of the cyclic stress-strain field in front of the fatigue crack with shear lips is discussed. The model curved crack front shape is chosen to closely correspond to the crack fron...

Constitutive model of tensile and shear fracture in timber
and shear fracture in timber has been proposed by the authors. The model applies the following rules for timber response: (a) pre-cracking response: elastic orthotropic behavior, (b)crack initiation: failure criterion acco...

Stress and Strain in Front of the Fatigue Crack With Shear Lips
Fatigue crack with curved front and shear lips in Al-alloy sheet was modelled using three-dimensional boundary and finite element methods. Local fracture with parameters of stress-plastic strain field ahead of the crack fro...

Three-dimensional morphology of fracture surfaces generated by mode II and III fatigue loading in ferrite and austenite.
This work is focused on an experimental study of shear-mode crack propagation. Three experimental setups are used for a generation of cracks in simple-shear, compact tension-shear and torsion specimens. Th...

Modelling of Tortuous Crack Fronts in Shear Loading Mode
The contribution is related to experiments on near-threshold fatigue cracks under shear modes II, III and II+III in bcc metals. Cylindrical bars with circumferential cracked notch were loaded by shear force. The no...

Analysis of the shear cracks in the prestressed thin-wall element and their effect on the deflection of the structure
prestressing arrangement also ensures avoiding of bending cracks and reducing bending stiffness. High attention must be given to the shear capacity of these elements and creation of the shear cracks. These cra...
