Abstract: A three-dimensional, transversely isotropic yield condition is combined with a plane of weakness to describe the initial yield limit for Green River Shale. This theory is compared to experimental ...

Abstract: Point Laser Triangulation (PLT) probes are relatively new noncontact probes being integrated with Coordinate Measuring Machines (CMMs). Two prominent advantages of PLT probes are fast measuring ...

Abstract: Point Laser Triangulation (PLT) probes have significant advantages over traditional touch probes. These advantages include throughput and no contact force, which motivate use of PLT probes on ...

Abstract: New commercial Point Laser Triangulation (PLT) probes enable Coordinate Measuring Machines (CMMs) to take faster, noncontact, accurate measurements. In this paper, we address how to apply this ...

Abstract: This paper presents a new technique for digitizing an unknown sculptured surface using a new multi-Laser Displacement Sensor (LDS) and an articulated Coordinate Measuring Machine (CMM). The new ...

Abstract: The surface of an elastic half space is subjected to sudden antiplane mechanical disturbances. Crack initiation and subsequent crack instability are examined via two idealized problems; the first ...

Abstract: The purpose of this paper is to report the results of finite element analyses of the collapse of perforated casing. In the study, both inline (0-deg phasing) and staggered (90-deg phasing) ...

Abstract: The effect of formation anisotropy on the hole deviation force acting on a single bit tooth is analyzed for a plastically deforming rock. A yield condition which allows a nonlinear dependence ...

Abstract: The demands to increase range, rate of fire, and muzzle velocity have resulted in increased wear and erosion problems in gun tubes. To increase the service life of gun tubes, a number of ...
