\(T_\text {D}^{(\mu \nu )}\) is the symmetrized stress-energy tensor (8) of the Dirac field. The l.h.s. of the field equation (12) is derived as the negative energy-momentum tensor of gravity, $$\begin{aligned} T_\text {G}^{\nu \mu }:= -g^{\nu \alpha } e^i{}...
8, 12 is a positive integer having a square factor then n() is not a subgroup of (), and then by using the results of Manin, Grauert, Samuel and Li on Mordell conjecture theorem for function fields, a similar result is established for function fields over an algebraically closed field...
However, unlike the shear area, where the shear stress distribution is defined for different shapes by a single equation, the shear stress distribution due to torsion is highly dependent upon the cross-section shape. In general, if the shear stress distribution function is available, it can be ...
In this context the theory reduces to General Relativity complemented by a dark stress-energy tensor due to the torsion of spacetime and is studied under the simplifying assumption of spherical symmetry. The dark stress-energy tensor is found to satisfy an anisotropic structure equation. In vacuum ...

Based on your understanding of the deformation of solids, explain the main differences between the stress-strain curves for brittle, ductile, and plastic material shown in the below figure. Give an example of a solid in each material. Show by direct substitution that equation psi (x...
The derived equation for the estimation of equivalent strain in HPT (Fig. 1) indicates that HPT processing is capable of reaching an unlimited amount of strain in a single operation due to the nature of the HPT process through the superimposition of hydrostatic pressure and torsion [15], [32...
of concrete in a square concrete-filled CFRP steel tubular flexural torsional members. It can be seen that the shear stress of the square members is roughly antisymmetric along the length direction. During the whole loading process, the maximum shear stress is always at the end of the concrete...
Average experimental and numerical results for the engineering stress–strain relationship, normalized root-mean-square deviation (NRMSD) = 4.67%. Figure 11. Average experimental and numerical results for the true stress–strain relationship, NRMSD = 0.91%. Figure 12. Average experimental and numer...
Dodging a falling door:: Reversing this equation gives us x=gt^2/2 as the fallen distance x for a given time t. How much time would you have to dodge a falling door if the spring were to suddenly break at the top of travel? Let us assume you are 5.5 feet tall, so the door wil...
