Virtual laboratory for measuring of elastic modulus with stress and strain for different metals

Abstract

Abstract The Colombian ministry of information and communications technologies is leading a digital revolution to bring computer and internet equipment to rural areas, taking into account that in these areas there are educational establishments that do not have equipment and materials for the performance of laboratories or experimental demonstrations. Therefore, this project proposed the development of a virtual learning laboratory for the study of the elastic modulus, obtained from real tensile-compression tests. It is important to clarify that there is not theoretical procedure to obtain stress-strain curves out of their linear regime. The virtual laboratory was developed in python language. The simulation allows the students to manipulate tensile-compression test for different materials. Also, they can visualization of the procedure, the stress-strain curve, and the Young modulus, all with the aim of transferring the conceptual and procedural knowledge of the physical phenomenon to the student.
