Discover tips to protect against eye strain when doing everyday activities and working on the computer. Strain may be either elastic, plastic, elastic and plastic, or viscoelastic. By a material per unit volume, the maximum amount of energy that can be absorbed without creating any permanent deformation in the elastic limit is known as modulus of resilience. Stress has a dimensional unit but the strain has no dimensional unit. It’s only when YOU reach your potential that your dental practice can as well. force (elastic strain), or the material may remain deformed, in which case the strain is non-recoverable(plastic strain). 3.1 ), as this mode is somewhat easier to understand than compression (a tensile specimen will be assumed unless otherwise specified).
