Abstract

This thesis discusses the analysis and relationship between stress and strain of beams with different types of materials. In addition an attempt will be make to draw together the various aspects of methods and applications of analysis in order to identify areas of relevance. The selected beams are manufactured by scaling down to laboratory-size specimen. This study also presents an analytical procedure for these beams. It examines the strain and load–deflection characteristics and proceeds to estimate the maximum load carrying capacity by taking into consideration the change of stress that occurs along the beam with the application of strain gauges. The analysis technique is divided into three main parts, which are theoretical, experimental and simulations. The first part is focused on the calculations of beams by using proper beam formulae. The second part is conducting experiment of bending stress for rectangular beam, I-beam and C-beam consisted of aluminium and mild steel. The third part is using Computer Aided Engineering (CAE) to verify the proposed analytical method. With the help of modern simulation tools such as Finite Element Analysis (FEA) this process has significantly been improved and simplified. In this research, the results of all analyze techniques are compared and briefly discussed. The accuracy of each technique can be determined based on analysis conducted and result obtained. The factor that affected the results has been identified and discussed such as type of materials, cross sections, the used of FEA, and errors involved. The relationship of stress and strain can be determined from the finding of this thesis which is stress is directly proportional to strain
