Mechanics of Winding Laminate Webs and the Prediction of Machine Direction Curl
(2019-05-01)
Winding models that describe the residual stresses due to winding single layer webs at the end of roll-to-roll manufacturing machines began development over 50 years ago. These models have been used to reduce or avoid ...
Modeling web handling systems and a method for determining feedback controller gains
(2020-07)
Modeling the longitudinal dynamics and control of web handling systems requires accurate models of the primitive elements involved, and an understanding of the processes used for speed and tension control. Primitive elements ...
Development of nonlinear finite element codes for stability studies of web material with strain state dependent properties
(2011-12)
Scope and Method of Study: The objective of the proposed research is to develop user friendly finite element codes that will solve nonlinear instability problems associated with strain state dependent material properties ...
