shear stress:剪向力 剪向力:物体由于外因而变形时，在物体内各部分之间产生相互作用的内力，以抵抗这种外因的作用，并力图使物体从变形后的位置回复到变形前的位置。在所考察的截面某一点单位面积上的内力称为应力。同截面相切的称为剪应力也称为切应力.shear strain:剪应变 剪应变:轴向拉伸或压缩的增量比原始量的极限是线应变，由于剪切里引起的错
“stress（或tension）”定义为单位面积上的力大小，该力是因为外力作用在物体上，而物体要产生反作用而产生的，其大小跟外力相同，但是大小相反。stress定义为：dF/dS，实际上就跟压强差不多了。stress可以分解为三个方向，其中一个方向跟参考面垂直，另外两个方向跟参考面平行（其实这是废话，任何的矢...
Non-linear shearLaminate mechanicsConstitutive lawThe majority of fiber reinforced composites exhibit strong non-linear behavior in in-plane shear state. The effect is attributed to the micro-cracks appearing in the matrix and can be modeled on the micro and macro level. In this work the author ...

Recently, to measure the stress-strain curve at an extremely high strain rate, the Taylor impact test [1] with the non-uniform nature of deformation in the specimen was used [2]. During the test, a high-speed camera [3–6] was introduced into the apparatus to record the deformation prof...

(P=0) at the outlet boundary. To describe the stress-strain relationship and blood viscosity, a generalized power-law constitutive equation for non-Newtonian fluids was applied and parameters were chosen based on published values39,40. COMSOL was able to calculate and export the values of wall ...
[Van Rooij et al., submitted for publication]. From this study was concluded that continuous blood flow simulations underestimated the shear rate by about 25% and overestimated the shear stress by a factor of two compared to cell-based blood flow simulations. In this study, the shear rate ...
