39 the stress strain diagram for a steel alloy having

Stress, strain, thermal conductivity, magnetic susceptibility and electrical permittivity are all second rank tensors. A third rank tensor would look like a three-dimensional matrix; a cube of numbers. Piezoelectricity is described by a third rank tensor. A fourth rank tensor is a four-dimensional array of numbers.

Figure 1 shows the stress-strain diagrams of the 09G2S steel at test temperatures from room temperature to 1200°C, and Figs. 2 and 3 show the dependences of the mechanical properties on the test temperature. At room temperature, the yield strength of the steel is σ 0.2 = 400 ± 25 MPa, the ultimate strength is σ u = 540 ± 14 MPa, and the relative elongation is δ = 28 ± 2%.

For example, a steel beam reacts differently to stress than a bungee cord. A measurement of the elasticity of a material is called the Young's modulus, and is determined as a ratio of stress to strain: Young's modulus (Y) = stress/strain. Young's modulus can be used in the following equation: F = Y (∆L/L0)A.

Tensile strength of steel is defined as the resistance of steel to breaking under tensile stress. It's used to define the transition from elastic deformation to plastic deformation in steel. It's usually expressed in force units per cross-sectional area. A piece of steel will break apart after it has been taken past its tensile stress limit.

For heat-treated plain carbon steels and mild steel alloys, the tensile strength (in psi) is roughly equal to 500 times the Brinell hardness. Rockwell hardness is determined by first using a minor load to force the indenter into the material and then, after equilibrium is reached, applying a major load.

To make the slope of the stress-strain curves of different materials comparable, two points on the curve have to be fixed. The first point will be the origin, the second the tangent to the curve.

The stress-strain graph provides engineers and designers a graphical measure of the strength and elasticity of a material. It allows them to predict the behavior of materials used in a given application. To draw the graph, the material must first undergo a tensile test. A tensile test is the simplest and most widely implemented mechanical test.

In order to clarify the creep mechanism of high Cr martensitic steel, creep curves of 9Cr-1W and 9Cr-4W steels were analyzed applying an exponential law to the temperature, stress, and time parameters.

Okay, so after my last post, there was a request for details about phase states other than what we can see documented in the TTT diagram. As I've been writing this, it's kind of evolved into a primer on the different phase states and what they mean. If my last post was too long for you, I'm sorry to say this one is probably longer. So, let's get ourselves started. The first thing we need to discuss is what is steel? What makes steel different from iron, and where does cast iron come into this m...

Remember: Steel may seem firm, but it's actually an elastic material. That means when you fasten a bolt, you are actually stretching the material. The stress applied to a bolt is known as "tensile stress" or "preload." In the graph below, you'll see stress graphed on the y-axis, while the amount of stretch on the fastener is shown on the x-axis.

**SME Atomic Scale Mechanism:** In the previous post I compared the Shape Memory Effect (SME) to an accordion, and will now relate the musical instrument to the SME on the atomic scale. Similar to an accordion, the martensitic structure that Nitinol forms is heavily twinned, or kinked in a symmetrical fashion along the lattice. [Here is a diagram for the rest of this paragraph](http://i.imgur.com/LtIrM.png). These kinks, or twins, in the crystal structure can be "stretched out" if a force is app...

**Aluminum Mechanical Properties:** As stated earlier, Al is an FCC metal. The critical resolved shear stress is only 1 MPa. That might not mean much all by itself, so first I'll quickly explain what the critical resolved shear stress is. Imagine a single crystal of aluminum in the shape of a cylinder. If you were to put a load P on the long axis of the cylinder, the crystal would deform but it WOULDN'T just squish the cylinder to make it fatter.
