Thermal Properties of Materials

In mechanical engineering, the thermal property is represented as the physical quantity that is relevant to the application of heat. The thermal properties are evaluated by variations in any specific material due to low heat or high heat. The quantities that influence the thermal property of the materials are mass, density, temperature, and many others.

### Stress-Strain Analysis of Aluminum 6061-T6

This data was collected from a tensile test demonstration for Aluminum 6061-T6. Below are the resulting stress-strain diagrams obtained from the test.

#### Left Diagram: AI 6061-T6 Stress-Strain Curve
- **Axes**: The horizontal axis represents strain (\(\varepsilon\)) in mm/mm, ranging from 0 to 0.15. The vertical axis represents stress (\(\sigma\)) in MPa, ranging from 0 to 350 MPa.
- **Curve**: The stress-strain curve illustrates the behavior of Aluminum 6061-T6 under tensile loading. The curve rises steeply, indicating the elastic region, and reaches a peak before dropping to zero, representing failure.

#### Right Diagram: AI6061-T6 Stress-Strain Curve, Magnified
- This magnified view highlights the elastic region for detailed analysis.
- **Axes**: The horizontal axis shows strain (\(\varepsilon\)) from 0 to 0.008, while the vertical axis shows stress (\(\sigma\)) from 0 to 300 MPa.
- **Features**:
- A yield stress line at approximately 270 MPa.
- A line illustrating the 0.2% offset method for determining yield stress.
- A marker at the intersection of the offset line with the curve, indicating the yield point.
- A stress value is marked at 220 MPa, and a strain value is indicated at around 0.0032.

#### Tasks for Estimation
Estimate the following properties:
a) **The modulus of Elasticity, \(E\)**
b) **The yield stress, \(\sigma_y\), using the 0.2% offset method**
c) **The strain at failure, \(\varepsilon_{\text{failure}}\)**
d) **The modulus of resilience (approximately)**

The magnified diagram aids in enhancing the details necessary for these estimations, particularly around the yield point and initial elastic region.
