Materials Engineering Lecture 1

Materials are the building blocks of everything around us. They are essential in all areas of engineering, including civil, mechanical, manufacturing, biomedical, electronics, and more.

This module explores the different types of materials, their properties, and the relationships between them.

This module provides an introduction to the diverse world of materials, covering key aspects like their classification, properties, and the relationship between the two.

This module helps you understand how different materials are used in engineering applications.

This module offers a foundation for understanding the importance of materials in engineering practices.

Steel is known for its strength, glass is known for its brittleness, diamond is known for its hardness, and rubber is known for its ductility.

Materials can be categorized based on their common properties. This helps us understand their suitability for specific engineering applications.

This module helps you understand how materials are classified based on their properties and how these properties contribute to their suitability for different applications.

Polymers that can be reprocessed into new products.

Inorganic materials that resist heat and chemicals well. They're often brittle and hard.

A type of ceramic material, often made of silicon dioxide.

Materials that are created by combining different classes of materials to get a specific set of properties.

A property that describes a material's resistance to breaking or cracking.

The ability of a material to resist deformation under applied stress.

The ability of a material to resist breaking under tension.

A measure of how easily a material can be deformed.

A material's resistance to scratching or indentation. Measured by the material's hardness. A hard material is difficult to scratch.

The breaking or cracking of a material under stress. Can occur due to various factors, including applied load, material properties, and environmental conditions.

The point at which a material can no longer withstand applied stress and fails. Can occur due to fracture, yielding, or other types of deformation.

Materials that are good conductors of electricity. They are often malleable and ductile.

Long chains of molecules that often have great flexibility and can be molded into various shapes.

Materials made by combining other materials to get desired properties.

The main component of a composite, providing overall structure.

The added material in a composite, improving specific properties.

Concrete, the matrix, is strong under pressure, while steel reinforcement adds strength under stretching.

Glass fibers are strong and stiff but brittle, while resin is flexible and holds fibers together.

Materials that have at least one dimension in the nanometer scale. This means they are incredibly small, about one million times smaller than a millimeter.

A sheet of carbon atoms arranged in a hexagonal lattice. It is known for its strength and ability to conduct electricity and heat.

A tube-shaped structure made of rolled-up graphene. It exhibits exceptional strength, electrical conductivity, and heat conductivity.

Materials found in nature and not significantly altered by human processes. Examples include wood, cotton, wool, and stone.

Materials categorized based on their specific functionality, properties, and applications. This includes materials like electronics, magnetic materials, and optical materials.

Materials that change their properties in response to external stimuli, like temperature, light, or magnetic fields.

Materials designed for use in biological systems, like implants, prosthetics, or drug delivery systems.

Materials used in aerospace applications, such as spacecraft, aircraft, and satellites. They often require exceptional strength, heat resistance, and lightweight properties.
