Normal stresses in surface shear experiments

Determination of normal and shear residual stresses from fracture surface mismatch

The contour method of residual stress measurement has recently been adapted to measure fractured, rather than cut specimens. The fracture contour method was capable of determining normal residual stresses acting prior to the planestrain failure of a large aluminium alloy forging, but shear residual stresses could not be measured (Prime et al., 2014, Eng. Fract. Mech., 116, 158-171). We demonstr...

Normal stresses in a shear flow of magnetorheological suspensions: viscoelastic versus Maxwell stresses

Shear Stresses in Shock-compressed Covalent Solids

Shear stresses are the driving forces for the creation of both point and extended defects in crystals subjected to high pressures and temperatures. Recently, we observed anomalous elastic materials response in shock-compressed silicon and diamond in the course of our MD simulations and were able to relate this phenomenon to non-monotonic dependence of shear stress on uniaxial compression of the...

Normal stresses in elastic networks.

When loaded in simple shear deformation, polymeric materials may develop so-called normal stresses: stresses perpendicular to the direction of the applied shear. These normal stresses are intrinsically nonlinear: basic symmetry considerations dictate they may only enter at O(γ(2)), with γ the dimensionless shear strain. There is no fundamental restriction on their sign, and normal stresses may ...

The Contribution of Cell Surface Components to the Neutrophil Mechanosensitivity to Shear Stresses

This review discusses the regulation of neutrophils by fluid shear stress in the context of factors that may govern cell mechanosensitivity and its influence on cell functions. There is substantial evidence that mechanoreceptors located on the peripheral membrane contribute to the ability of shear stress to regulate cell activity. In the case of neutrophils, the formyl peptide receptor (FPR) an...
