The Young's modulus is the ratio of the stress-induced in a material under an applied strain. The strain is the amount of deformation in the material, such as the change in length in an extensional experiment, expressed as a fraction of the beginning length. The stress is the force exerted on the
Storage modulus (G') is a measure of the energy stored by the material during a cycle of deformation and represents the elastic behaviour of the material. Loss modulus (G") is a measure of the energy dissipated or lost as heat during the shear cycle and represents the viscous behaviour of the
The storage modulus can be increased through several methods including: 1. Material composition modifications, 2. Crosslinking density enhancement, 3. Temperature control during processing, 4. Addition of fillers or reinforcements. One significant aspect is that the ** material composition
