Diverse patterns of pebbles on sand on Mars and Earth
Zheng Zhu, Bernard Hallet, András A. Sipos +3
On Mars, fields of sand dunes contrast with the general cratered, rocky terrain commonly seen from orbit. Near the equator, in Gale Crater, images from the rover, Curiosity, also r…
Reconstruction of early phase deformations by integrated magnetic and mesotectonic data evaluation
A. A. Sipos, E. Márton, L. Fodor
Markers of brittle faulting are widely used for recovering past deformation phases. Rocks often have oriented magnetic fabrics, which can be interpreted as connected to ductile def…
Shape of an elastica under growth restricted by friction
Marcell G. Horváth, András Á. Sipos, Péter L. Várkonyi
We investigate the quasi-static growth of elastic fibers in the presence of dry or viscous friction. An unusual form of destabilization beyond a critical length is described. In or…
The Mullins effect in the wrinkling behavior of highly stretched thin films
Eszter Feher, Timothy J. Healey, Andras A. Sipos
Recent work demonstrates that finite-deformation nonlinear elasticity is essential in the accurate modeling of wrinkling in highly stretched thin films. Geometrically exact models…
Tracking critical points on evolving curves and surfaces
Gábor Domokos, Zsolt Lángi, András A. Sipos
In recent years it became apparent that geophysical abrasion can be well characterized by the time evolution of the number of static balance points of the abrading parti…
Explaining the elongated shape of 'Oumuamua by the Eikonal abrasion model
Gábor Domokos, András A. Sipos, Gyula M. Szabó +1
The photometry of the minor body with extrasolar origin (1I/2017 U1) 'Oumuamua revealed an unprecedented shape: Meech et al. (2017) reported a shape elongation b/a close to 1/10, w…
Disappearance of stretch-induced wrinkles of thin sheets: a study of orthotropic films
Andras A. Sipos, Eszter Feher
A recent paper (Healey et al., J. Nonlin. Sci., 2013, 23:777-805.) predicted the disappearance of the stretch-induced wrinkled pattern of thin, clamped, elastic sheets by numerical…
Ooid growth: Uniqueness of time-invariant, smooth shapes in 2D
Andras A. Sipos
Evolution of planar curves under a nonlocal geometric equation is investigated. It models the simultaneous contraction and growth of carbonate particles called ooids in geosciences…
How river rocks round: resolving the shape-size paradox
G. Domokos, D. J. Jerolmack, A. Á. Sipos +1
River-bed sediments display two universal downstream trends: fining, in which particle size decreases; and rounding, where pebble shapes evolve toward ellipsoids. Rounding is known…
Circular, stationary profiles emerging in unidirectional abrasion
G. Domokos, G. W. Gibbons, A. A. Sipos
We describe a PDE model of bedrock abrasion by impact of moving particles and show that by assuming unidirectional impacts the modification of a geometrical PDE due to Bloore exhib…
A discrete random model describing bedrock profile abrasion
Andras A. Sipos, Gabor Domokos, Andrew Wilson +1
We use a simple, collision-based, discrete, random abrasion model to compute the profiles for the stoss faces in a bedrock abrasion process. The model is the discrete equivalent of…
The mechanics of rocking stones: equilibria on separated scales
Gábor Domokos, András Árpád Sipos, Tímea Szabó
Rocking stones, balanced in counter-intuitive positions have always intrigued geologists. In our paper we explain this phenomenon based on high-precision scans of pebbles which exh…
Formation of sharp edges and planar areas of asteroids by polyhedral abrasion
G. Domokos, A. Á. Sipos, Gy. M. Szabó +1
While the number of asteroids with known shapes has drastically increased over the past few years, little is known on the the time-evolution of shapes and the underlying physical p…
