October 30, 2019, 06:33	Curve fitting for Ogden models in Workbench ANSYS	#1
SteFanI New Member Join Date: Aug 2019 Posts: 10 Rep Power: 6	Hi Can someone please tell me whether the Ogden model takes stress/strain as inputs in ANSYS Workbench and uses a curve fitting method to calculate MU and ALPHA? I have loads and displacement data from Instron Machine. They are not stress/strain. Do I need to convert them prior plugging them into the Ogden model or the Ogden model does it automatically and yields stress/strain from loads/displacement?
