WebBolt stressed by bending. The additional bend in the connecting screws must be avoided as the resulting bending stress can be several times greater than the tensile stresses of prestressing and operating forces. The causes of the additional bending moment can be divided into two groups. One group of causes is production inaccuracy. WebSep 12, 2024 · Tensile strain is the measure of the deformation of an object under tensile stress and is defined as the fractional change of the object’s length when the object experiences tensile stress. tensile strain = ΔL L0.
