Unlike VTK objects, one can set the properties of a tvtk object when the object is initialized by passing the properties (traits) of the object as keyword arguments at the time of class instantiation. Whereas a plot of stress versus total strain using linear hardening, Figure 1(f), has a post yield slope that is called the elasto-plastic modulus and it is not the same as the plastic modulus. Understanding these performance indicators with the use of CFD simulation enables engineers to explore more ideas and make better decisions. 3The three greater-than signs denote the user input for the Python interactive session, with the result, if there is one, shown on the next line.
