Thanyarat Singhanart Faculty of Engineering, Chulalongkorn University 2012 Abstract Studying material properties carefully can be an important improvement for engineering design. It will help reducing number of product failures and be able to determine the range of applications that each material can be used. In material selection, we consider many properties of material so that we would select a material that suitable for the application. Mechanical properties testing are required to test each material for us to learn about mechanical properties of each material. There are 3 standard tests that are famous on testing the material. Those are tensile test, impact test and hardness test. Introduction Material selection is an important designing process since in many failure products come from using the wrong material, so selecting material would required a study on properties of each material, then compare the material properties to choose the material suited for the application. The important material properties that commonly considered are chemical property, physical property and mechanical property. Chemical property refer to the structure of material and its formation. Physical property relate to science of physics that can be measure while not destroying the material. Mechanical property shows the characteristic of the material after force is applied, normally relates to elastic and plastic behavior of the material and often measurements are obtain by destruction of material. Motivation Mechanical properties are one of the important properties that are commonly considered for material selection. Inspecting
