Design and Fabrication of Portable Tensile Testing Machine for Poly-mers & Filaments

This research project presents the design and development of a portable tensile testing apparatus intended for determining the tensile characteristics of polymer-grade tensile specimens. The project also highlights the rationale for using compact tensile testing machines as effective alternatives to conventional large-scale tensile testing systems currently employed in laboratories and industries. Tensile testing is a widely used experimental method for evaluating the mechanical properties of polymers, primarily to determine parameters such as tensile strength and the maximum elongation before fracture. The project is divided into two major phases: design and fabrication of the tensile testing machine. The mechanical design of the system is developed using UG NX software, following which the apparatus is fabricated and experimentally tested. The performance results obtained from the fabricated machine are analyzed to validate its functionality and effectiveness.
