Variation of youngs modulus with temperature

Click For Summary
SUMMARY

Young's modulus of elasticity is indeed dependent on temperature, as confirmed by the discussion. As temperature increases, thermal expansion causes an increase in bond length, which results in a decrease in the forces holding atoms together. This reduction in atomic bonding force directly influences the macro-scale elastic modulus, leading to variations in Young's modulus with temperature changes.

PREREQUISITES
  • Understanding of Young's modulus and its significance in materials science.
  • Knowledge of atomic bonding and thermal expansion principles.
  • Familiarity with the relationship between temperature and material properties.
  • Basic grasp of elasticity concepts in physics.
NEXT STEPS
  • Research the effects of temperature on Young's modulus in various materials.
  • Explore the principles of thermal expansion in solids.
  • Study atomic bonding forces and their impact on material elasticity.
  • Investigate experimental methods for measuring Young's modulus at different temperatures.
USEFUL FOR

Materials scientists, mechanical engineers, and students studying the effects of temperature on material properties will benefit from this discussion.

Does youngs modulus of elasticity depend upon temperature?

But why??

But why??

Roughly, the force holding atoms together in bonds decreases as the bond length increases, which happens during thermal expansion. This force is the origin of the macro-scale elastic modulus.
