QUESTION:
The stress-strain diagram shown has been drawn from data obtained during a tensile test of an aluminum alloy. Using E = 72 GPa, determine (a) the modulus of resilience of the alloy, (b) the modulus of toughness of the alloy.
ANSWER:
Step 1 of 5
We have to calculate the modulus of resilience for different grades of steel given. The modulus of resilience can be determined using the following formula:
Where:
is the modulus of resilience
is the yield strength
is the modulus of elasticity
Modulus of Elasticity of the steel (E) is .
