Virtual laboratories have a very important place for distant education which has real applications of laboratory tests and experiment applications. It is fact that virtual laboratories necessity is inevitable because of the requirements of materials, place, staff and above all, time and financial requirements for establishment of real laboratories. The main concept of virtual laboratory is to replace real machines with their virtual simulations. Real investigative equipment is not often available for students, researchers, and practitioners as users in addition to their expensive costs in usage. Virtual laboratories are cheap and safe in use because all mistakes can be easily erased by web-based application or simulation reset without any consequences. Furthermore users can easily make many tests regardless of place in any time on the web. In this study AISI 4140 steel was used, since AISI 4140 steel is the most well-known type of steel used in industries. Tensile test of the steel was examined regarding to different tensile speeds. The study aimed to design the web-based virtual tensile test laboratory. The uniqueness of this study is generating an artificial neural network model by using the values of the material which is stressed in different speeds. Thanks to this model, intermediate speed values were predicted. Besides that, this model was used to design web-based virtual tensile test laboratory application. With the help of this application, users can easily realize the yield strength, ultimate strength and fracture strength on stress-strain diagram.
