Material Classification

Non-metallic materials include plastics, ceramics, and composites, which lack metallic bonding and typically exhibit different electrical, thermal, and mechanical properties.
Examples of non-metallic materials: rubber, glass, and wood.

Mechanical Properties

The ability to resist being pulled apart is known as tensile strength, which indicates how much force a material can endure before failing.
Mechanical properties often include tensile strength, compressive strength, ductility, hardness, and elasticity.

Force Types

Shear force acts to cause layers of material to slide past each other, leading to deformation at an angle to the force applied.

Stress and Strain

Tensile stress is calculated using the formula: Tensile Stress = Force / Cross-sectional Area.
Shear stress occurs when applied forces act parallel to the surface of a material.
Average strain is determined by the formula: Average Strain = Change in Length / Original Length.

Effects of Forces

A body subjected to compressive stress typically shortens in length, which can lead to buckling or deformation.
Strain represents the deformation of a material relative to its original length, reflecting how much a material stretches or contracts under applied stress.

Test your knowledge on the classification of engineering materials into metallic and non-metallic materials, as well as the properties of metallic materials such as physical, mechanical, and chemical properties.
