Tensile test :- Introduce:- Tensile test property often are measure during development of new material and process , tensile property often are used to predict the behavior of a Material under forms of loading other than uniaxial tention. 1)-Tensile specimen and test machines. 2)- stress -strain curve , elastic versus plastic deformation. 3)-yield point , Ductility 4)-test methodology and analysis 5)-True stress and strain. Test methodology and data analysis:- 1.sample selection. 2.sample preparation.  3.Test setup. 4.Test procedure.  5.Data recording and analysis. 6.Reporting. Yield Strength Take the minimum yield in psi of the ASTM grade (see our Strength Requirements by Grade Chart for this value), multiplied by the stress area of the specific diameter (see our Thread Pitch Chart). This formula will give you the ultimate yield strength of that size and grade of bolt. Shear Strength :- First, find the ul...
