This book presents the design and implementation of a universal testing machine for mechanical characterization of metals and polymers in three-point bending and tensile test, adapting a control system, monitoring and data visualization, using specialized equipment for automation. The parameters to carry out; tensile, three-point bending tests and the functional and technical specifications that the machine must have according to ASTM standards were defined. Concept design, mathematical calculations and CAD designs were developed using Solidworks. Graphical User Interface (GUI) was designed...
