WebApr 10, 2024 · Based on the elastic and plastic nature of the materials, different types of behaviour of the material can be seen, which can be explained using Hooke’s law. The … WebElasticity is the measure of the amount that the object can return to its original shape after these external forces and pressures stop. [2] This is what allows springs to store elastic potential energy. The opposite of …
WebDec 18, 2024 · This is the elastic behavior of that material. Every material has an elastic limit which defines the maximum limit that material turns into the initial shape like above. … WebAbove the elastic limit, the material exhibits plastic behaviour Elastic deformation occurs in the ‘elastic region’ of the graph. The extension is proportional to the force applied to the material (straight line) Plastic deformation occurs in the ‘plastic region’ of the graph.
WebBelow the elastic limit, the material exhibits elastic behaviour. Above the elastic limit, the material exhibits plastic behaviour. The elastic region is where the extension is … WebNo real body is perfectly elastic. Even within the proportional limit, there will be microfractures (minute). So, there will be some degree of deformation if a body is …
WebApr 6, 2024 · Plastic deformation needs a greater amount of force. Within this elastic zone, Hooke's Law of Elasticity applies. If the material is plastically distorted, Hooke's Law does not apply. Within this elastic area, most solid materials exhibit linear stress-strain behaviour. In the plastic zone, the stress-strain curve is non-linear.
