Deformation analysis: the Caspary approach [PDF]

open access: yesGeodetski Vestnik, 2020
In this paper, the theoretical background of the Caspary method of geodetic deformation analysis is described and implemented in a simulated geodetic network in which two epochs of measurements are used.

Measurement and analysis of brain deformation during neurosurgery. [PDF]

open access: yes, 2003
Recent studies have shown that the surface of the brain is deformed by up to 20 mm after the skull is opened during neurosurgery, which could lead to substantial error in commercial image-guided surgery systems.

Finite deformation analysis of geomaterials [PDF]

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, 2001
AbstractThe mathematical structure and numerical analysis of classical small deformation elasto–plasticity is generally well established. However, development of large deformation elastic–plastic numerical formulation for dilatant, pressure sensitive material models is still a research area.In this paper we present development of the finite element ...

Design by analysis of ductile failure and buckling in torispherical pressure vessel heads [PDF]

open access: yes, 2008
Thin shell torispherical pressure vessel heads are known to exhibit complex elastic-plastic deformation and buckling behaviour under static pressure. In pressure vessel Design by Analysis, the designer is required to assess both of these behaviour modes ...

Mechanical behaviors of surrounding rock and supporting structure of shallow-buried unsymmetrical pressure tunnel crossing soil–rock interface

open access: yesFrontiers in Earth Science, 2023
Shallow bias tunnels are sensitive at the entrance section, where the existence of soil–rock interface (SRI) results in more complex deformation of surrounding rock and supporting structure.

Analysis of laminated shells by a sinusoidalshear deformation theory and Radial Basis Functions collocation, accounting for through-the-thickness deformations [PDF]

open access: yes, 2011
In this paper, the static and free vibration analysis of laminated shells is performed by radial basis functions collocation, according to a sinusoidal shear deformation theory (SSDT).

WAVELET DEFORMATION ANALYSIS FOR SPHERICAL BODIES [PDF]

open access: yesInternational Journal of Wavelets, Multiresolution and Information Processing, 2005
In this paper, we introduce a multiscale technique for the analysis of deformation phenomena of the Earth. Classically, the basis functions under use are globally defined and show polynomial character. In consequence, only a global analysis of deformations is possible such that, for example, the water load of an artificial reservoir is hardly to model ...

Analysis of functionally graded sandwich plates using a new first-order shear deformation theory [PDF]

open access: yes, 2014
In this paper, a new first-order shear deformation theory is presented for functionally graded sandwich plates composed of functionally graded face sheets and an isotropic homogeneous core. By making a further assumption to the existing first-order shear

Static and vibration analysis of functionally graded beams using refined shear deformation theory [PDF]

open access: yes, 2013
Static and vibration analysis of functionally graded beams using refined shear deformation theory is presented. The developed theory, which does not require shear correction factor, accounts for shear deformation effect and coupling coming from the ...
