Molecular Mechanics Simulations of Instabilities in 3D Deformations of Gold Nanospecimens
… quite different when it is deformed with some bounding surfaces free from external forces as opposed to essential boundary conditions prescribed on all bounding surfaces. It is found that the initial unloaded configuration (or the reference configuration) of the minimum potential energy has …

Three-dimensional eolian bounding surface architecture of the Entrada sandstone, Utah: expanding our understanding of reservoir heterogeneity in wet eolian systems
Eolian bounding surfaces represent significant changes in dune-field dynamics caused by allogenic and autogenic processes associated with erg evolution. Eolian deposits form noteworthy petroleum reservoirs (e.g., Norphlet Formation, Rotliegend Group, and the Tensleep Sandstone), but bounding …

Finite Coupled Torsion and Inflation of Functionally Graded Mooney-Rivlin Cylinders with and without Residual Stresses
… deformations caused by pressures applied to the bounding surfaces and axial loads or twisting moments on the end faces. We also simulate residual stresses in a hollow cylinder either by inverting it inside out or by closing a longitudinal wedge opening parallel to the cylinder axis through …

Simulating Blast Effects In Steel Skeletal Structures
… structural component is derived that uses bounding surface plasticity models, defined in stress-resultant space, to represent the effects of the blast by way of a plastic reduction matrix. Each bounding surface is created by generating numerical failure data for a given component and …

INTERNAL FACIES ARCHITECTURE OF A REGRESSIVE TO TRANSGRESSIVE WAVE-DOMINATED DELTA IN THE UPPER CRETACEOUS EAGLE FORMATION, SOUTH-CENTRAL MONTANA
… internal stratigraphy, facies architecture, and bounding surfaces of the lower Eagle provide the basis for reconstruction of a paleodelta system that serves as a valuable reservoir analog within the Cretaceous Seaway and elsewhere. This study demonstrates that the informal lower member of the …

Buckling and postbuckling of flat and curved laminated composite panels under thermomechanical loadings incorporating non-classical effects
… I), the kinematic continuity at the contact surfaces between the contiguous layers and the free shear traction condition on the outer bounding surfaces are satisfied, whereas in the second model (Model II), in addition to these conditions, the static interlaminae continuity requirement is …

A multidisciplinary approach to reservoir characterization of the coastal Entrada erg-margin gas play, Utah
… and muddy interdune facies, and first order bounding surfaces. Many of the sandstone bodies within the outcrop belt are genetically related and in communication with each other. This relationship results from dune complex migration to the south and up section over time. Stratigraphic climb …

On iso- and nonisothermal crack problems of a layered anisotropic elastic medium
… The crack is assumed to be parallel to the layer bounding surfaces. By employing the Fourier integral transform technique and the flexibility/stiffness matrix formulation, the current mixed boundary value problems are reduced to solving a set of simultaneous singular integral equations with …

3D GROUND-PENETRATING RADAR (GPR) INVESTIGATIONS: BURIED CULVERTS, HISTORICAL GRAVES, A SANDSTONE RESERVOIR ANALOG, AND AN IMPACT CRATER
… bedding (0.6 m) and the extent (9 m) of major bounding surfaces. In the fourth case of “craters” I used 3D GPR to image ejecta elements and to map the alluvium thickness at the Barringer (Meteor) Crater in Arizona. Some software was developed to assist the processing. Workflows were developed …
