The ultimate tensile strength is usually found by performing a tensile test and recording the engineering stress versus strain. The highest point of the stress–strain curve is the ultimate tensile ...

The basic idea of a tensile ... strength of the material just as it starts to permanently change shape. It is determined as the value of the stress at which a line of the same slope as the initial ...

The top diagram shows a tensile stress-strain curve for a 6,6 Nylon. It should be noted that the strain at fracture is very large (300%) compared to that for metals. The lower diagram shows the ...
