Simulation of Inspecting Stress Concentration with Thermoelastic Stress Analysis

Article Preview

Abstract:

The thermoelastic stress inspecting stress concentration was simulated using element plane223 of software ANSYS, comparing the result of simulation analysis and theory calculation, the simulation results of temperature and stress are precise extremely when the specimen is loaded sinusoidal load; the temperature changes of the right node in hole border is 0.305°C and the temperature changes of the bottom node in hole border is 0.098°C, the simulation results error comparing to the theory value are respectively 0.33% and 3.92%,which meets the real need. The temperature change value can be inspected with regular infrared camera, it will be a reliable method for inspecting and locating cracks in steel bridges.
