### How can I describe cold work and atomic structure?

A copper wire (42 cm x 0.25 cm diameter) twisted to failure did not change its dimensions significantly. How can I visualize or quantify the cold work done (tensile at the exterior, compressive in the ...

### Shear modulus in terms of 2 Young's moduli and Poisson ratio

I have two moduli, EY and EZ, and the poisson ratio NUYZ, and the equation for the shear modulus that I am using is $G = \frac{EY*EZ}{EY+EZ+2*EY*NUYZ}$ but I am not sure where it comes from. I tried ...

### How do FE solvers solve the case of panel buckling under pure shear?

How do FE solvers solve the case of panel buckling under pure shear? The main problem is that global matrix of initial stess is singular in that case. One method is to apply some forces that shear is ...

### How do you ensure that a beam is loaded through the shear center?

Reading about shearing stresses in beams, it is commonly stated that it is necessary to load a section through its shear center, so no twisting is applied to the beam. This is specially important in ...

### Physical Significance of Max Shear Stress in a Rod in Compression

For a rod in compression, the max shear stress at a point is $\pm\sigma_x/2$, i.e. half the compressive stress applied at either end. This value is obtained using the equation for $\sigma_\theta$, ...
