Tectonic collision processes after plate rupture
Tectonophysics, 1987Abstract Rupture of a continental plate subducted below a forearc produces a fold and thrust mountain belt with fast overthrusting of nappes. Post-rupture plate unflexing leading to reflexure provides a mechanism for foreland basin formation. Application to the Australia-Banda Arc collision accounts for the origin of the Timor Trough, its imbrication

Atherosclerotic plaque rupture: a fatigue process?
Medical Hypotheses, 2000The mechanism of atherosclerotic plaque rupture is not known. Current theories focus on the acute triggers of plaque rupture and myocardial infarction such as increased shear or circumferential stress, rupture of the vasa vasorum and vasospasm. We hypothesize that a critical mechanism causing plaque rupture is fatigue failure, the catastrophic rupture ...

Constituent Processes and Democratic Ruptures
American Journal of Comparative Law, 2016This paper is a review of Gerardo Pisarello’s book, Procesos Constituyentes: Caminos para la Ruptura Democratica. This book examines constitution-making as a global phenomenon, both from a historical and comparative perspective. The author of this paper proposes that a more decisive move from the descriptive to the normative would have been desirable ...

Dynamical fault rupture processes in heterogeneous media
Tectonophysics, 1987Abstract The fault rupture processes in a horizontally layered medium and also in a three-dimensionally heterogeneous structure are investigated on three-dimensional, spontaneous dynamic shear crack models. The wave equations for three-dimensional space are solved numerically by a finite difference scheme under the appropriate boundary conditions and

Brittle Melt Rupture Phenomena in Polymer Processing
International Polymer Processing, 1997Abstract In this contribution the various rupture mechanisms which can occur during the elongation of polymer melts will be briefly reviewed, with the focus on the cohesive brittle melt rupture. Observations of melt rupture phenomena during polymer processing operations will be discussed.

Rupture instability in hydroforming deep-drawing process
International Journal of Mechanical Sciences, 1985Abstract The critical fluid-pressure locus above which rupture by tensile instability may occur in the hydroforming deep-drawing process, is formulated and tested. The formulation is based on the classical theory of plasticity (with simple power-law hardening and Mises-Hill normal anisotropic yielding) assuming plane strain tensile failure.

Can Extensional Flow Rupture Macromolecules in an Electrospinning Process?
Journal of Polymer Science Part B: Polymer Physics, 2017ABSTRACTThe fracture of high molecular weight poly(ethylene oxide) (PEO) chains under extensional stretching during the electrospinning of aqueous solutions was investigated by measuring solution viscosities and monitoring the change of molecular weight.

Damage–Rupture Process of Concrete Dams Under Strong Earthquakes
International Journal of Structural Stability and Dynamics, 2014A new concept for establishing the damage model for high concrete dams under earthquakes based on damage mechanics is presented in this paper. Unlike the conventional approach of considering the residual deformation by means of plastic-damage coupling, the proposed approach relates the degraded apparent elastic moduli of loading and unloading directly

Atherosclerotic plaque rupture: local or systemic process?
Arteriosclerosis, thrombosis, and vascular biology, 2003It is generally established that the unstable plaque is the major cause of acute clinical sequelae of atherosclerosis. Unfortunately, terms indicating lesions prone to plaque instability, such as "vulnerable plaque," and the different phenotypes of unstable plaques, such as plaque rupture, plaque fissuring, intraplaque hemorrhage, and erosion, are ...

Stochastic Rupture Process of Fault Patches
1997Fluctuation phenomena with 1/f spectrum have been observed in a wide variety of dissimilar physical systems, where f is frequency. Noise experiments in electronic devices reveal the fractional power spectrum of 1/f α type. It is known that noise currents in semiconductors and turbulent flow fields are described by fractional power spectra of 1/f 3/2 ...
