Common mechanical Material properties

The mechanical properties of a material are the measure of how it responds to an applied force. This is determined by the stiffness, strength, maximum load bearing capacity, and other physical properties of the material. The following is a list of common mechanical materials properties

Stiffness

Strength Maximum load bearing capacity Physics of Torsion Torsion is defined as twisting. Torsion is defined as twisting. When a structure is subjected to torques the structure changes shape and the stress and strain of the structure change accordingly.

When a structural element is subjected to torsion, it is then known as torsional. Torques can be applied to a material in several ways, the most common being the twisting of the axis of rotation. Torque is a change in the direction of rotation of a material. Torques can be applied to a body in two primary ways..

Strength

Lowest strength is the ability to resist being pulled or pressed by some force. Stiffness Most commonly used, a stiff material is strong enough to resist or absorb an applied force without breaking. Thickness Usually used to describe the range of height that a load can be applied to a material without causing permanent deformation or failure.

Maximum load bearing capacity

Maximum load bearing capacity is measured as the load that a material can absorb before breaking. This is often described as the load you can stand on it before it falls over. Resistance to shearing Shearing occurs when a material breaks, due to the force between two surfaces.

The strength of a material is usually related to its ability to shear, meaning the strain energy (fraction of elastic modulus) required to break it. Composite material The word composite refers to the natural materials that come together to create an effect similar to a single material. It can also refer to substances that can be molded or formed using heat. Strength The strength of a material is determined by its modulus of elasticity, which is the ability of a material to absorb and deliver stress.

Other mechanical properties

Some properties of the material which are not listed above include:

1. Strain – The ratio of the change in a material when it is stretched.

2. Violation – Another measure of how elastic a material is.

3. Shear rate – Measure of how fast the material deforms when put under stress.

4. Uniaxial and shear strength – Uniaxial strength is related to the flexural modulus of the material and shear strength is related to the sagittal modulus of the material.

Strain, shear and uniaxial strength are all related to the geometric dimensions of the material. The properties listed above are relative to the material’s other physical properties. The linear stiffness, force-velocity ratio, deformation rate, and rate of change in properties (shear rate) are related.
