Experimental report Name: Tutor: Course: Date: Introduction Materials testing is the actual process of assessing the properties of the material. It is a lengthy process that aims at determining the finer property details of the materials. Engineering materials are tested for their strain so as to determine their failures.
Quality assurance plays an active role in materials testing. Quality assurance carries out calibration test and manufacturing test. Calibration test is carried out to determine the workability of the measuring properties. Manufacturing test is carried out to determine the adherence to standardization. Some of the tests through which engineering materials are subjected to can be categorized as follows; Mechanical test These tests are carried out on the engineering materials to determine their strength, elastic constants, material properties and performance properties. Mechanical test involves testing the test specimen. The test specimen is obtained through the breaking of the original sample materials. Tensional test These are quasi-static test carried out on the engineering materials to determine the properties of these materials. This test is carried out by exposing the sample material to uniaxial loading conditions. Hardness test The resistances to penetration by most engineering materials are determined by hardness test. Hardness test is carried out using three different methods that are scratch test, rebound test, indentation test. Scratch test involves progressive scratching of a hard material. Rebound test involves the ability to determine the material resilience. Material resilience is determined by measuring the potential energy of the material. ...
