Transcription of Structure and Mechanical Properties of Materials
1 Structure and Mechanical Properties of MaterialsIntroduction 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 materialsThe 14 Bravais LatticesSolidification of a Polycrystalline MaterialGrain BoundariesThe Three Common Types of MaterialsIntroduction to Carbon PolymersThe unit at the base ofCarbon Chains3-D Representation of a chain of single bonded carbonsCarbon chains can only rotates in specific waysIntroduction to Carbon PolymersBranching in PolymersCross-Linking in PolymersMulty-Component PolymersMulti-Component PolymersMechanical Properties of MaterialsFundamentals of Elastic BehaviorBasic Types of Loading and DeformationsDefinition of StressTensile StressShear StressDefinition of StressDefinition of StrainTensile
