Journal ArticleDOI
Celebrating the 100th anniversary of the Stoney equation for film stress: Developments from polycrystalline steel strips to single crystal silicon wafers
TL;DR: In this paper, a modified form of the Stoney equation, well known for elastic isotropic substrates, is derived for Si(001) and Si(111) wafers, using the elastic stiffness constants of silicon, cij, instead of the orientation averaged values E and ν, which do not have a meaning for elastically anisotropic single crystal materials.
Journal ArticleDOI
Review of options for structural design sensitivity analysis. Part 1: Linear systems
TL;DR: In this paper, the authors present a review of different approaches to sensitivity analysis in structural problems, including global finite differences, continuum derivatives, discrete derivatives, and computational or automated differentiation.
Journal ArticleDOI
Characterizing size-dependent effective elastic modulus of silicon nanocantilevers using electrostatic pull-in instability
Hamed Sadeghian,C.K. Yang,Johannes F.L. Goosen,E. van der Drift,Andre Bossche,P.J. French,F. van Keulen +6 more
TL;DR: In this article, the authors presented the application of electrostatic pull-in instability to study the size-dependent effective Young's Modulus of [110] silicon nanocantilevers (thickness ~1019-40nm).
Journal ArticleDOI
Simulation of fracture healing incorporating mechanoregulation of tissue differentiation and dispersal/proliferation of cells
TL;DR: A numerical algorithm is presented incorporating both mechanoregulation and evolution of cell populations, and it proves capable of predicting realistic difference in bone healing in a 3D fracture callus.
Journal ArticleDOI
Development and experimental validation of a three-dimensional finite element model of the human scapula.
TL;DR: Considering the complicated testing procedure on a fresh sample of scapula, the high correlation coefficients, the low standard errors and percentage errors in the regression slope, strongly suggest that the strains calculated by the FE model can be used as a valid predictor of the actual measured strain.
