Question

what accounts for the wide range of elastic modulus tension values for the materials?

Elastic Modulus: Tension (GPa) (Linear / Log) 1000 Elastic Modulus: Tension (GPa) Edit Elastic Modulus: Tension (GPa) O COXO + Metal 00 OOOXO + Polymer OO DODO + Ceramic + Composte • 0200 + Advanced Max 950 950 • 000 Low High

Answer 1

Elastic modulus is material property which depends on atomic bond strength . Atomic bond strength depends on nature of bond. When we change the temperature of material elastic modulus changes. When we increase the temperature bond strength decreases .

Metals have higher bond strength as compared to other

Hence in graph we can see it has smaller range . That means with change in temperature E elastic modulus changes significant for material with low bond strength like polymer.
