Static compression test of materials

Abstract

A static compression test is a technique in which a material is subjected to a rising compressive stress for a set period until failure occurs. It's used to figure out a material's ultimate yield strength, service life, and other key performance indicators. To ensure the accuracy and precision of the overall study, specific testing procedures and methods must adhere to the experiments by working closely with the American Society for Testing and Materials (ASTM) International Standards E9-19, the Standard Test Methods of Compression Testing of Metallic Materials at Room Temperature. Static compression testing on four medium and four long Aluminium Alloy 6061-T6511 rods will be done during this Final Year Project (B183) using the Shimadzu AG-X plus 100kN equipment. It begins with the specimen being placed between two Shimadzu testing machine fixed compression plates, with an applied force progressively increasing up to 100kN. Strain values will be measured using strain gauges affixed to the surface of the specimens. Finally, the experiment’s results will be compiled for further study. The goal of this experiment is to identify and compare material properties such as Young’s Modulus, strain, stress, and the yield strength of the long and medium-length specimens. Graphs of Stress-Strain and Force-Displacement will be plotted using data from the TrapeziumX Software and the Data logger for a proper investigation of the materials properties. The date collected will be analysed and compared to previous reports, to acquire ideal results that are consistent with the material’s mechanical properties. Finally, recommendationsfor future researchers will be provided to reach a higher degree of accuracy and precision
