The Stress and Strain Analysis Training Unit is specifically designed to demonstrate the fundamental principles of direct stresses and strains that develop within a cylindrical structure when subjected to internal pressure. The system consists of a cylindrical test specimen, which is pressurized internally using a hydraulic pump to simulate real-world conditions where components experience internal forces. As the internal pressure increases, the cylinder undergoes deformation, allowing users to observe and analyze the resulting stress distribution and strain variations within the material
- The Stress and Strain Analysis Training Unit is designed to investigate direct stresses and strains in a thick-walled cylinder subjected to internal pressure.
- The test cylinder is filled with oil and constructed of a rigid aluminum cylinder where the pressure is applied from one end using a hydraulic piston.
- Due to the cylinder›s wall thickness, stress distribution across the wall is non-uniform and must be analyzed accordingly.
- Strains can be measured on definite position on the cylinder to determine the stresses conditions.
- Strain gauges are used to electrically record strain data with high accuracy.
- A pressure gauge displays the internal pressure of the cylinder.
- Additional strain gauge is installed on the surface of the cylinder to determine the surface strains
- The unit allows measurement of radial, hoop (circumferential), and axial strains, enabling a complete analysis of the strain state.
- The system can be connected to a measuring amplifier that converts strain signals into readable values.
- The machine enables correlation between strains and internal pressure and stresses, also graphical correlations between the resulting stresses and the internal pressure.
- The unit includes software that applies Mohr’s circle to visualize and interpret the triaxial stress state acting on the specimen.
