Formability of Sheet Metal Under Non-Coaxial and Zig Zag Strain Paths
… drawing, the deformation in the work-piece is coaxial owing to axial symmetry; in other words, during the forming operation, the principal axes of stress and strain coincide with each other and are fixed with respect to the material. The directions of the principal axes are along the meridional …

Constitutive Modelling of Shear Localisation in Saturated Dilative Sand
… deformation of dense sand is evaluated. Then non-coaxial and non-associative flow theories are integrated. Different flow rules are examined for proportional and non-proportional loading paths. Both theories inhibit the tendency to dilate. Non-coaxial Nor-Sand model reduces the overly stiff …

Structural Characteristics and Tectonic Evolution of the Pirineus Syntaxis, Central Brazil
… that the two limbs formed during separate, non-coaxial deformation events. This interpretation implies that the Brasilia belt itself formed as a result of at least two non-coaxial episodes. These episodes may reflect sequential collision of microcontinents with the western margin of the Sao …

Zero modes and degrees of freedom of topological solitons on the plane
In this thesis we analyse the coaxial multivortices of the Ginzburg-Landau, the Euclidean complex sine-Gordon-1 and -2 theories on the plane. More specifically, we determine the number of continuous free parameters describing the largest family of solutions, with these vortices as members. This is …

Vorticity of Flow, Deformation Temperatures, and Strain Symmetry of the Moine Thrust Zone, NW Scotland: Constraining the Kinematic and Thermal Evolution of a Collisional Orogenic System
… flattening strain with only a minor rotational (non-coaxial) component. In contrast, deformation in the Moine nappe was strongly non-coaxial, as indicated by asymmetric single girdle c-axis fabrics. Quartz c-axis opening angles and microstructures suggest that deformation temperatures increase …

Aspects of the structure, tectonic evolution and sedimentation of the Tygerberg terrane, southwestern Cape Province
… the contact and it is proposed that it is non-coaxial to, and late relative to the ca 600Ma orogenic episode. The oblate nature of the strain ellipsoid lends support to the mechanism of radial distension as a means of pluton emplacement. An insight into the effect of the deformation on the …

An investigation of the electromagnetic coupling problem by means of a rational framework and selected experiments
… and the measurement of moments between non-coaxial permanent magnets. Both experiments were designed and conducted in this work. For the corresponding theoretical investigations, an efficient finite element method in curvilinear coordinates is developed. The method is also used to …

Polyphase Deformation, Thrust-Induced Strain and Metamorphism, and Mesozoic Stratigraphy of the Granite Wash Mountains, West-Central Arizona (Tectonics, Mylonite, Geophysics, Mineralization, Terranes)
… gneiss. It may be Early Mesozoic. Three non-coaxial phases of deformation affect the Mesozoic rocks of the GWM. The first event (D1) resulted in a megascopic ENE-trending, SSE-facing tight recumbant syncline, which is associated with slaty cleavage. D2 folds refold D1 structures and are …

Microstructural and crystallographic fabric analysis of stretched-pebble conglomerates in central Vermont
… by grain boundary sliding, therefore only coaxial portions of the strain are recorded by the matrix quartz lattice preferred orientation. Furthermore, strain partitioning, and possibly the lack of extensive recrystallization, has precluded the development of strong lattice preferred …
