Another class of materials used in MST is composites, which are made of a combination of materials (such as S T R U C T U R E O F M AT E R I A L S CH1 AND CH3 V. R AG H AVA N THE INTERNAL STRUCTURE OF A Phi Long Nguyen. crystobalite Silicate ceramics (continue) Though there are many levels of structure (e.g., atomic vs. macroscopic), many phys-ical properties of a material can be related directly to the arrangement and types of bonds that make up that material. This edition now includes more stream- Silicates are materials composed primarily of silicon and oxygen ( soils, rocks, clays, sand, and glass) Silica, silicon oxide (SiO 2), • Three crystal structures: quartz, cristobalite, and tridymite • Open structure, not close-packed, low density Si4+ O2-Adapted from Figs. Chapter 3. Sections 5.3-5.4. • Properties • Performance Needs for materials (i.e. Introduction to Material Properties •New Focus on: –Fundamental information on the bulk properties of biomaterials –Basic level to enable understanding of metallic, polymeric, and ceramic substrates •In the next few classes we will cover: –Crystal structure –Stress-strain behavior –Creep, fracture, fatigue, and wear of materials 3.2 Fundamental Concepts. Structure of Materials An Introduction to Crystallography, Diffraction and Symmetry This highly readable, popular textbook for upper undergraduates and graduates compre-hensively covers the fundamentals of crystallography, symmetry, and diffraction, and applies these concepts to a large range of materials. Materials science and technology is a multidisciplinary approach to science that involves designing, choosing, and using three major classes of materials—metals, ceramics, and polymers (plastics). The Structure of Materials 1.0 INTRODUCTION AND OBJECTIVES A wealth of information can be obtained by looking at the structure of a material. • Material properties generally vary with single crystal orientation (i.e., they are anisotropic), but properties are generally non-directional Bulk Material Properties (PDF - 1.4 MB) Crandall, Dahl, and Lardner. ... University of Illinois 7 Materials Science Investigating the relationship between structure and properties of materials. Chapter 3-9 3.3 Unit Cells Chapters 4-5. Crystal Structures •A crystalline material is one in which the atoms are situated in repeating or periodic array over large atomic distances. amorphous structures. • Lattice means a three-dimensional array of point coinciding with atom positions. Reinforced Composite Materials : (reinforced concrete, reinforced plastics) One of the most important task of an engineer is to select the most suitable material for a given civil engineering structure. Wood also could be used. Ashby, and Jones.

Introduction to Engineering Materials Processing-Structure-Property-Performance. the system of the applied forces and the material behavior The behavior of a material can be studied by means of mechanical testing Stress vs. strain diagrams are often used to describe the material behavior Stress vs. strain diagrams are supposedly/theoretically identical for the same material, but technically there is always some differences
