A controllable ferroelastic switching in ferroelectric/multiferroic oxides is highly desirable due to the non-volatile strain and possible coupling between lattice and other order parameter in heterostructures. However, a substrate clamping usually inhibits their elastic deformation in thin films without micro/nano-patterned structure so that the integration of the non-volatile strain with thin...
A two-point orientation auto-correlation function (TP-OACF) was developed in order to quantify the spatial distribution of targeted texture components. An example of a TP-OACF was demonstrated using an idealized orientation map. Characteristics of the spatial distribution of major texture components in 6022-T4 Al sheets deformed in plane-strain tension were also quantified using a TP-OACF. The ...
The response of a neo-Hookean fiber composite undergoing finite out-of-plane shear deformation is examined. To this end an explicit close form solution for the out-of-plane shear response of a cylindrical composite element is introduced. We find that the overall response of the cylindrical composite element can be characterized by a fictitious homogeneous neo-Hookean material. Accordingly, this...
Material and methods Prospective comparative study in Centre des Massues (Lyon). Study of a group of 10 adolescents aged 10 to 15 for whom a 3D spine analysis was made before and after brace treatment, using Optispine software. The parameters of interest were correction of the Cobb angle, sagittal curves, and plane of maximal deformation (percentage of vertebrae in the plane, rotation, flexion,...
This paper briefly reviews progres~ in the elastic plastic analysis of crack extension. Analytical results for plane strain and plane stress deformation fields are noted, and elastic-plastic fracture instability as well as transitional behavior and combined rate and thermal effects are discussed.
We analyze a thin elastic, homogeneous strip under a smooth load and several different types of boundary conditions. The strip is assumed to obey either a plane strain or a plane stress type deformation of linear theory of elasticity. We characterize the 2D solution and consider dimension reduction of arbitrary order n. Both interior and global energy estimates for the reduction error are derived.
Forming limit diagrams (FLDs) are calculated based on both the Marciniak and Kuczynski (M-K) model and the analysis proposed by Jones and Gillis (J-G). J-G analysis consisted of plastic deformation approximation by three deformation phases. These phases consisted of homogeneous deformation up to the maximum load (Phase I), deformation localization under constant load (phase II) and local necki...
