Chapter outline: Classes of materials (categories of materials) Materials selection criteria Material properties Commonly used material of construction Materials fabrication steps Economic selection of materials Analysis of failure for metals (types of failure, finding primary cause of failure and initiate corrective action to prevent repetition). Classes of materials Materials selection criteria The most important characteristics (criteria) to be considered when selecting a material of construction ...
Statics and Strength of Materials Statics is the study of forces acting in equilibrium on rigid bodies • “Bodies” are solid objects, like steel cables, gear teeth, timber beams, and axle shafts (no liquids or gases); • “rigid” means the bodies do not stretch, bend, or twist; • “equilibrium” means the rigid bodies are not accelerating. In Strength of Materials, we keep ...

Importance • Physiotherapy interventions are required after any acute injury in the form of a complete rehabilitation intervention. • Major role of physiotherapy involves the assessment of patient’s needs and abilities so that the Orthotists can prescribe and fabricate correct and effective orthosis for the patients. • Physiotherapy also plays a keen role in preparing the patients to keep up with the orthosis and ...
Content Introduction Ceramic Matrix Nanocomposites • Type of CMN • Processing Metal Matrix Nanocomposites • Type of MMN • Processing Introduction of Nanocomposites Nanocomposites- solid structures with nanometer-scale dimensional repeat distances between the different phases that constitute the structure Typically consist of: • Inorganic(host) solid containing an organic component or vice versa • OR consist of 2 or more inorganic/organic phases in some combinatorial form ...
Overview In today’s lesson we will turn the most common & most used materials into a Nanocomposite Concrete pumper Credit: AllMix UK In a Conventional Lab Is normally achieved using equipment & This nanotechnology supplies like this • Cryo-crushing • Micro-grinding • Powder milling Powder mill Credit: Shanghai Clirik Machinery Co., Ltd In a “Kitchen Lab” Can be achieved (emulated) using ...
Nanomaterials for Building Addition of nanoscale materials into cement could improve its performance, It is found that nano-SiO could significantly increase the compressive for concrete, containing large volume fly ash, at early age and improve pore size distribution by filling the pores between large fly ash and cement particles at nanoscale. It has also been reported that adding small amount of carbon nanotube (1%) by ...
Stress - Normal/Direct shear • Mechanics of Materials • Study of internal effects caused by external loads • Considers real bodies that deform (statics assumes no deformation) • 3 main concerns • Strength - Will it _____________________? • Stiffness - Will it _____________________? • Stability - Will it ______________________? 2 Stress • Defined as the intensity of an internal force • forc In equation form: ...
