Tensile rock mass strength estimated using InSAR

evaluation of rock mass deformability

One of the most important effective parameters in design of engineering structures is deformability of rock mass. Benchmark of rock mass deformability is the deformation modulus that directly or indirectly obtained. Since the determination of rock mass deformation modulus indirect method by in-situ tests is time-consuming, costly and difficult from executive operations aspect, so it’s correctly...

Yield & Tensile Strength of Steel & Aluminium Using Microindentation

Water's tensile strength measured using an optofluidic chip.

In this paper, for the first time, the tensile strength of water is directly measured using an optofluidic chip based on the displacement of air-water interface deformation with homogeneous nucleation. When water in a microchannel is stretched dynamically via laser-induced shock reflection at the air-water interface, the shock pressures are determined by measuring the displacements of the defor...

RADARSAT InSar Monitoring of an Active Rock Avalanche

In this study, we used RADARSAT interferometrically derived images to monitor current post slide motion at the Frank Slide, a 30x 10m rock avalanche, in the Canadian Rockies. The images cover the period from September 2000 to April 2004. Our results show that the Frank slide is still active and the deformation process is localized and related to seasonal and local weather conditions. This infor...

Bacterial adherence to high--tensile strength sutures.

PURPOSE The purpose of this study was to evaluate the bacterial adherence to high--tensile strength suture materials using a bioluminescent in vitro model. METHODS Eleven strands each of No. 2 MaxBraid (Arthrotek [Biomet], Warsaw, IN), FiberWire (Arthrex, Naples, FL), Ethibond (Ethicon, Somerville, NJ), Orthocord (DePuy Mitek, Raynham, MA), and silk (Ethicon) sutures were immersed in a broth ...
