Measurements were also made at a two-dimensional upstream station. The data show the development of the various terms of the tensor as well as their relative orders of magnitude. One surprising result was that the measured u1u3 shear stresses were substantial at the inlet to the curved channel...
The results show that pore pressure stress coupling has a tensor character and can cause significant changes in the stress field within the reservoir as a function of distance to the injection point and tectonic regime. The tensor character of pore pressure/stress coupling leads to changes in the...
Since the sign of m0 and n0 is not significant, Ψ must be an even function of m0 and n0, and so it may be expressed as Ψ=ΨC,M0,N0 where M0 = m0 ⊗ m0 and N0 = n0 ⊗ n0 are structural tensors. Based on the kinematic description, the SEF can be rewritten in the ...
\vec {e}_2)associated withq_1andq_2can be expressed as a single rotation\text {Rot}(\omega , \vec {e}) = q_2 q_1. Concatenation, however, is not commutative (q_2 q_1 \ne q_1 q_2) and a different order of consecutive rotations results ...
Consider a solid body Ω crossed by a crack surface Γc where the displacement is discontinuous. The strong form of the equilibrium equation is:∇·σ+ρb=0inΩwhere σ is the Cauchy stress tensor and b is the body force. The boundary condition on the fracture surface Γc is:-σ·n...
Parameter determination in elastic analysis of jointed rock masses by crack tensor theory. Stress strain relations of rock masses are considerably different from that of intact rocks due to the presence of geological discontinuities such as joint...

We show that the stress-energy-momentum of affine-metric gravity as like as the Noether current in gauge theory is reduced to a superpotential on shell.关键词: Tensor methods Classical field theory Field theory models Gauge field theory Internal symmetries ...
The macroscopic and microstructural properties of several packings subjected to biaxial compression are analyzed as a function of particle elongation. We find that the shear strength is an increasing linear function of elongation. Performing an additive decomposition of the stress tensor based on a ...
Another approach consists on evaluating the shape of the six-dimensional (6D) path described by the six normal and shear components of the stress tensor, where the stress path contour is interpreted as a homogeneous wire with unit mass. The moment of inertia (MOI) tensor of this hypothetical ...
Stressintensityis defined as the largest of the absolute values(最大绝对值)of σ1-σ2, σ2-σ3, or σ3-σ1: Stress intensity is related to the maximum shear stress: σI=2τmax Elastic Strain intensity is defined as the largest of the absolute values(最大绝对值)of ε1- ε2, ε2...
