A = tensile stress area of the bolt (square inches, m2) strain Stress Area The tensile stress area can be calculated as A = (π / 4) (d - 0.9743 / n)2 (2) where d = nominal diameter of bolt (in) n = 1 / p = number of threads per inch p = pitch, length per thread...
Take the minimum yield in psi of the ASTM grade (see ourStrength Requirements by Grade Chartfor this value), multiplied by the stress area of the specific diameter (see ourThread Pitch Chart). This formula will give you the ultimate yield strength of that size and grade of bolt. Example:W...
"ratio ofstress(force per unit area) along an axis tostrain(ratio of deformation over initial length) along that axis" It can be used to predict the elongation or compression of an object as long as the stress is less than the yield strength of the material. More about the definitions be...
Standard ANSI Hardware Fastener - Bolt Design Calculations (This calculator requires a java - enabled browser) This calculator calculates the tensile stress area of a external screw thread of a fastener. Use this calculator for materials over 180,000 psi ultimate tensile strength....
Stress relaxation behavior of two turbine bolt steels was evaluated by the manualcontrolled tensile stress relaxation test (TSRT) at high temperature. First, feasibility and the procedure of the manual-controlled tensile stress relaxation test (TSRT) is discussed and carried out on a general creep...
The ultimate tensile strength formula is: S = F / A where S = the breaking strength (stress) F = the force that caused the failure A = the least cross sectional area of the material The ultimate tensile stress (UTS) is typically found in a more precise manner by performing a tensile ...

reduction for holes. In case of a single angle member connected by one flange only, the net area shall be reduced by 10 %. For connections with one bolt only, the net area shall be reduced with 30 %. Allowable ultimate tensile stress is equal to 重音在紧张成员从净区域将被计算在减少...
Tensile strength is the maximum amount oftensile stressa material can withstand before it fails or breaks. It is a measure of the material's ability to resist deformation under tension or stretching forces. When high tensile loads are applied,ductileand brittle materials will approach failure. This...
