... Deformation of Semicrystallineand crosslinkedPolymers Deformation of Amorphous Polymers TENSILE RESPONSE: ELASTOMER CASE üModuliof elasticity for polymers are ~ 10MPa-4GPa (compare to metals ... hundreds of MPato several GPa) üElongation can be up to 1000 % in some cases (< 100% for metals) üPolymers are also very sensitive to the rate of deformation (strain rate). Decreasing rate of d...
