Calculate Modulus of Toughness (MT)



Formula

The formula to calculate the Modulus of Toughness (MT) is:

\[ \text{MT} = 0.5 \cdot \sigma \cdot \epsilon \]

What is Modulus of Toughness?

The modulus of toughness is an indicator of a material’s ability to absorb energy up to the point of fracture. It is defined as the area under the stress-strain curve from the origin to the point of fracture. This property is crucial in applications where materials are subjected to impact and must not fail catastrophically.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Modulus of Toughness:

\[ \text{MT} = 0.5 \cdot 500 \text{ MPa} \cdot 0.02 = 5 \text{ MPa} \]

The Modulus of Toughness is 5 MPa.
