Physics of Materials

The properties of various materials are explained using physics. These materials include composite materials, biomaterial, electric material, electronic material, viscoelastic material, structural material, power generating material. Composite materials provide desirable characteristics and required properties for specific design and testing, and so they are preferable in many applications of engineering than their metallic equivalent. As biomaterial, Tumor Cell DU145 is presented and its reproduction is illustrated. As an electronic device, solar cell is constructed by local materials, which are cheap, available and safe. A lumped system model is developed in which the thermocouple approached higher temperature as time got larger. As a viscoelastic material, asphaltene exhibits interesting properties. Fuzzy system can predict these properties more accurately than other methods. Using the wind speed as renewable energy source, wind turbine generator produces electric power. For structural materials, cracks in materials and changes in stiffness are identified by lamb waves propagating in it.
