tensile stress - stress that tends to stretch or lengthen the material - acts normal to the stressed area compressive stress - stress that tends to compress or shorten the material - acts normal to the stressed area English. Stress is a physical quantity.

21 июн 2020 The maximum horizontal stress SHmax directions and tectonic regime change at local scale displaying a very heterogeneous stress field and 

Läs mer. The stressed area depends on the type of threads - coarse threads reduces the stressed area compared to fine threads. UN and UNR Bolts Tensile Stress Area. The stressed area in a bolt can be calculated as. A = (π / 4) (d n - 0.9743/ n) 2 (1) where. A = stressed area (in 2) d n = nominal bolt diameter (in) Stress is a physical quantity.

Stress is defined as the force per unit area of a material. i.e. Stress = force / cross sectional area: where, σ = stress, F = force applied, and. A= cross sectional area of the object. Units of s: Nm-2 or Pa. Notice how localized this stress peak stress region is. The average stress across the bulk of the section is around 31,000 psi.
