Mechanical deformation mechanisms and properties of amyloid fibrils
Physical Chemistry Chemical Physics, 2015We study the role that the length of amyloid fibrils plays in their mechanical deformation mechanisms and properties by using all-atom explicit water steered molecular dynamics simulations.

Mechanical Deformation Mechanisms in Knitted Fabric Composites
Journal of Thermoplastic Composite Materials, 1997Knitted fabric composites have certain advantages over woven composites, particularly in their ability to conform to complicated contours. As a consequence, however, they demonstrate inferior mechanical characteristics compared to woven materials as a direct result of the presence of bent fibers.

QUANTUM DEFORMATIONS OF QUANTUM MECHANICS
Modern Physics Letters A, 1993Based on a deformation of the quantum mechanical phase space we study q-deformations of quantum mechanics for qk=1 and 0<q<1. After defining a q-analog of the scalar product on the function space we discuss and compare the time evolution of operators in both cases.

The deformation mechanisms of hcp metals are more complex and less well investigated than those of, for example, face-centered cubic (fcc) and body-centered cubic (bcc) metals [4,12–15].

Origin and Mechanism of Postnatal Deformities
Pediatric Clinics of North America, 1977The child's skeleton must be thought of as a dynamic organ-formed, moved, and remodeled but unchanged. However, if the normal balance of the skeleton's environment is disturbed, the unchanging form also becomes disturbed and deformity occurs. This disruption of the environment may be mechanical imbalance, vascular insufficiency, metabolic abnormality ...

The basic problem in the study of the Earth’s crust is to understand its deformations. Unfortunately, the general physics of deformations is not as well understood as one might desire.

Abstract If all images in a pattern were presented in their pure form to the observer the task of pattern analysis would be drastically simplified compared to what is usually the case: the observed images are degraded versions of the pure ones.

Mechanical Deformation of Polyurethanes
Journal of Macromolecular Science, Part B, 2004Abstract The mechanical properties of thermoplastic polyurethanes (TPU) depend upon their composition and the complex two‐phase morphologies, which originate from microphase separation of chains segments. In the present work, poly(ether‐urethanes) were prepared with hard segment contents from 36% to 71% by weight, by systematically varying the length ...

The Mechanism of the Deformation of Clay
Clays and clay minerals (National Conference on Clays and Clay Minerals), 1953AbstractKaolinite-water mixtures, containing from 23 percent to 33 percent water, were subjected to compression plastometer tests and their plasticity was studied by means of the calculated strain-stress functions. X-ray diagrams taken of the compressed samples showed that an oriented texture developed during the compression, i.e., the basal planes of ...

Nanoscale Deformation Mechanisms in Collagen
2008The mechanical properties of collagen Type I tissues are, like many biological connective tissues, crucially dependent on the hierarchical architecture at the nanometer and micron length scale. Triple helical collagen molecules aggregate into ordered fibrils of ∼ 100–200,nm diameter, which in turn can form parallel-fibered fiber bundles or lamellae at ...
