DOI: 10.1016/j.ijsolstr.2018.03.020
Abstract: A stress-gradient material model was recently proposed by Forest and Sab [Mech. Res. Comm. 40, 16--25, 2012] as an alternative to the well-known strain-gradient model introduced in the mid 60s. We propose a theoretical framework… read more here.

DOI: 10.3390/mi13081169
Abstract: Thin film through-thickness stress gradients produce out-of-plane bending in released microelectromechanical systems (MEMS) structures. We study the stress and stress gradient of Al0.68Sc0.32N thin films deposited directly on Si. We show that Al0.68Sc0.32N cantilever structures… read more here.
