Abstract

The purpose of this research is to investigate the sheeting mechanic of the laminated material. The detailed mechanical behavior of plastic film is studied through some complex testing which includes uniaxial tensile test, tensile cyclic and stress relaxation test. The main objective of this project is to develop a low cost programmable tensile tester using LEGO Mindstorm system associated with the MATLAB function for mechanical testing of plastic film. A thin LDPE plastic film with a thickness of 0.01mm was selected as the specimen for the mechanical tests. In uniaxial tensile test, the LEGO tensile tester performed an uniaxial stretch of a sample while measuring the tensile force simultaneously. The results obtained from tensile tester were compared with the result obtained from texture analyzer. From the results obtained, the graphs of stress versus strain of the specimen are plotted to show their relationship. It was found that texture analyzer produced a noisy curve plot while LEGO tensile tester produced a smoother curve. The texture analyzer was able to stretch the plastic specimen until fracture point at 40m/m of strain, but LEGO tensile tester reached its maximum elongation of stretching at 0.6m/m of strain resulting in an unbroken plastic film. Besides that, the tensile cyclic and stress relaxation behavior of specimens was analyzed and discussed based on its mechanical characteristics. Finally, the results of this project were concluded and suggestions for improvement on further research were discussed.
