Five strain curves of pressure testing machine

The strain curve of the pressure tester can be divided into five forms.

Soft and weak: the tensile strength is low, the modulus of elasticity is small, and the elongation is not great.

Hard and brittle: the tensile strength and modulus of elasticity are larger, and the elongation at break is small.

Hard and strong: tensile strength and modulus of elasticity, and have a proper elongation.

Soft and tough: the elongation at break is large, the tensile strength is high, but the modulus of elasticity is low.

Hard and tough: the elastic modulus is large, the tensile strength and the elongation at break are also large.

These five kinds of curve form can directly reflect the sample reflected under tensile force of the state, ingenious pressure testing machine is here, it not only reflects the parameters, but in a form similar to the stock fluctuation curve of the performance, we will be able to grasp the curve used test specimen the performance and make use of the
