Rupture Dynamics of Macromolecules

2013
In a series of studies we consider the breakage of a polymer chain of segments, coupled by anharmonic bonds under applied tensional force or subject to rise in temperature. The chain dynamics at the onset of fracture is studied by means of Molecular Dynamics simulation and also using analytic considerations.A deeper insight into the changes in polymer ...

DYNAMICS OF A2 FINGER PULLEY RUPTURE

Journal of Mechanics in Medicine and Biology, 2007
A mathematical model of the A2 pulley system will enable us to have a better understanding of the mechanics of the pulley-tendon system and provide us with insights of the pulley rupture mechanism. The A2 pulley was modeled based on parallel pulley fibers attached to a phalanx with a tendon passing them.

Rupture dynamics of shock-tube diaphragm

2017 First International Conference on Recent Advances in Aerospace Engineering (ICRAAE), 2017
Diaphragm rupture process in a shock tube was studied through transient simulations. With the help of ANSYS Explicit Dynamics, the rupture process occurring in a shock-tube was simulated. Diaphragms of several thicknesses and scores were analysed. It was possible to predict the pressure difference at which rupture would take place which would help in ...

Dynamic stress changes during earthquake rupture

Bulletin of the Seismological Society of America, 1998
AbstractWe assess two competing dynamic interpretations that have been proposed for the short slip durations characteristic of kinematic earthquake models derived by inversion of earthquake waveform and geodetic data. The first interpretation would require a fault constitutive relationship in which rapid dynamic restrengthening of the fault surface ...

Support Operator Rupture Dynamics on GPU

2012 International Conference on Computer Science and Information Processing (CSIP), 2012
The method of Support Operator (SOM) is a numerical method to simulate seismic wave propagation by solving the three dimension viscoelastic equations. Its implementation, the Support Operator Rupture Dynamics (SORD) has been proved to be highly scalable in large-scale multi-processors calculations.

Dynamic rupture experiments elucidate tensile crack development during propagating earthquake ruptures

Geology, 2009
We used optical experiments and high-speed photography to interpret the origins of tensile fractures that form during dynamic shear rupture in laboratory experiments. Sub-Rayleigh (slower than the Rayleigh wave speed, c_R) shear ruptures in Homalite-100 produce damage zones consisting of an array of tensile cracks. These cracks nucleate and grow within

Rupture and dynamic hardness of ice

Doklady Physics, 2004
Imperfection of the available tension procedure is associated with the appearance of the bending moment, stress concentrations at the fastening points of samples, and initial slackness of loading systems. These factors are responsible for the distortion of the tension diagram even in its initial section [2, 3].

Dynamic Knee Stability After Anterior Cruciate Ligament Rupture

Exercise and Sport Sciences Reviews, 2003
A functional classification scheme has been devised to study knee stabilization strategies after anterior cruciate ligament rupture. A screening examination can determine which patients may be candidates for nonsurgical treatment (potential copers). A rehabilitation program that includes support surface perturbations can improve the potential coper's ...

Earthquake rupture dynamics frozen in exhumed ancient faults

Nature, 2005
Most of our knowledge about co-seismic rupture propagation is derived from inversion and interpretation of strong-ground-motion seismograms, laboratory experiments on rock and rock-analogue material, or inferred from theoretical and numerical elastodynamic models.
