Thermal stress analysis
Posted 14/03/2013, 11:34 GMT-04:00 Heat Transfer & Phase Change, Materials, Structural Mechanics & Thermal Stresses Version 4.2a, Version 4.3, Version 4.3a 6 Replies
i have analysed thermal stress by passing the laser beam on rectangular plate (through structural mechanics module).i used stainless steel temp dependent material properties to my simulation. i used elasto plastic properties yield and tangent modulus. i have attached the properties also.i satisfied with results of deformation of plate and temperature profile. but my major problem is von mises stress exceed the ultimate stress level.
how can i reduce the stress value??
is there any possible to use smooth function.
please help me genius.
