This model can be applied with satisfactory results to many different metals but for some materials its application can lead to an inaccurate material response.
The specimen thickness is 2 mm and all specimen have been cut from bulk material with the longitudinal axis parallel to the rolling direction.
The optimized VOCE material parameters for each test are summarized in Table 1.

It is a topic worthy of discussion about choosing the right materials according to the level of textbook and the characteristics of students.
In order to teach the contents to students well, it is necessary to integrate the teaching materials.
Then the students look up materials, select control indicators and the appropriate experiment method, design a testing program independently.
