Stress Strain Curve For Metals Ceramics And Polymers

The stress strain curve is the simplest way to describe the mechanical properties of the material.

Stress strain curve for metals ceramics and polymers.

The brittle polymer red curve elastically deforms and fractures before deforming plastically. After plotting the stress and its corresponding strain on the graph we get a curve and this curve is called stress strain curve or stress strain diagram. The blue curve is a plastic polymer and is similar to curves for many metals. Primarily differences are due to their different chemical bonding properties homework 1.

Stress strain curves for metals ceramics and polymers objective we are interested about studying and comparing stress strain curves of metals ceramics and polymers. Stress strain curves for two brittle materials. For brittle ceramics a three point bending apparatus shown in the figure below is used determine the stress strain behavior and the measurement results are used to calculate an equivalent modulus of elasticity. In this the stress is plotted on the y axis and its corresponding strain on the x axis.

Polymers exhibit a wide range of stress strain behaviors as shown in the figure below. The stress strain curve can provide information about a material s strength toughness stiffness ductility and more. Strain is the percent change in the length of the material.
