Types of stress in physics are... 1) Tension 2) Compression 3) Torsion 4) Bending 5) Shear
When you weld something, it'll cool unevenly. This will set up stress points in the matrix that can cause problems like warping and reduction of strength. Stress relieving seeks to correct this.
The relation between bending moment and the second moment of area of the cross-section and the stress at a distance y from the neutral axis is stress=bending moment * y / moment of inertia of the beam cross-section
direct stress is a stress normal to the cross section, A, and is the result of an axial load, P. direct stress = P/A Bending stress also acts normal to the cross section but varies from tension on one side and compression on the other. and is the result of a bending moment, M. bending stress = Mc/I where I is the area moment of inertia and c the distance from outer fiber to neutral axis
Assuming linear elastic bending with small deformations and planes perpendicular to the neutral axis remain plane after bending, then for a rectangular beam: Moment = (Yield Stress)*(Second Moment of Area)/(Distance of surface to Neutral Axis) For Ultimate Bending Moment, assume stress is uniform throughout the beam, and acting through half the distance from surface to neutral axis, then: Moment = Stress * (Area/2)*(h/4 + h/4) For a better visualization check out Popov's textbook, Engineering Mechanics of Solids, Chapter 6, Section 6.10
I need to calculate the stress resulting from a torsion moment on a hollow steel section as well as a flat plate.
Bending is another common stress that materials experience, in addition to tension, compression, and torsion. When a material undergoes bending, one part of it is in tension while the other part is in compression due to the applied load or moment.
Warping in materials like wood or plastic is typically caused by uneven stress or moisture absorption. When one side of the material expands or contracts differently than the other, it can lead to warping. Proper storage and handling can help prevent warping.
Under torsion only, the shear stress is minimum, in fact zero, at the center point ( where radius is zero)
Yes.Modulus of RuptureUltimate strength determined in a flexure or torsion test. In a flexure test, modulus of rupture in bending is the maximum fiber stress at failure. In a torsion test, modulus of rupture in torsion is the maximum shear stress in the extreme fiber of a circular member at failure. Alternate terms are flexural strength and torsional strength.
A Stress fracture
The warping wall can weaken the structural integrity of the building by causing uneven stress distribution and potential structural damage.
Shear and torsion forces are a combination of bending stress. This stress characterizes the behavior of a structural object subjected to an external load, which is applied perpendicular to the axis of the object.

30-degree fibers in composite materials are oriented to optimize their ability to handle both compressive forces and torsional loads. When subjected to compressive forces, these fibers can convert the compressive stress into tensile stress by redistributing the load along their length, effectively resisting buckling. In the case of torsion, the 30-degree orientation allows for better shear resistance, as the fibers align with the direction of the applied torque, enhancing their tensile capabilities. However, while 30-degree fibers offer advantages in these scenarios, the optimal fiber orientation may vary depending on specific loading conditions and material properties, suggesting that a tailored approach is often necessary for maximizing performance.

It is torsion and tension while tightening, and pure tension when tightened
