WebEngineering Stress Units for stress and conversion factors • Load per unit area (“force distribution”) – PSI: 1 lb/in2 = 6.895 x 10-3 MPa = 7.032 x 10-4 kg/mm2 = 6.8 x 104 dynes/cm2 – MPa: 1 MPa = 1 MN/m 2= 1 N/mm = 1 x 106 N/m •An engineering stress, as defined above, represents the average stress in the object. appliedloadWebJul 23, 2013 · Convert true stress - plastic strain to nominal stress - strain. Simply export true stress and plastic strain from your simulation results and run the code. this code converts them to true stress - true strain and nominal/engineering stress - strain which now is comparable with input. This code will help to double check the material property.
