Workspace analysis is one of the most important issues in the robotic parallel manipulator design. ‎However, ‎the unidirectional constraint imposed by cables causes this analysis more challenging in the cabledriven redundant parallel manipulators. Controllable workspace is one of the general workspace in the cabledriven redundant parallel manipulators due to the dependency on geometry parameter...

A detail field and microscopic characteristics of Malayer Plutonic Rocks (162-187Ma), west of Iran, are discussed in details to evaluate relationships between deformation and pluton emplacement. The studied rocks were injected into the slate, phyllite and schists of so called "Hamadan phyllites and slates" in the Sanandaj-Sirjan zone. Studies have shown that there is a continuity from magmatic ...

Up to now, the effect of strain rate on adhesive bond shearing resistance stiff clay, which plays a fundamental role in constitutive modeling such kind soils, remains unclear. This paper aims experimentally investigate dependency clay. Both undisturbed and reconstituted overconsolidated samples Merville clay from Flanders region north France are prepared with different overconsolidation ratios ...

A hardening response is often observed for shear-dominated large deformation of Carbon Fibre Reinforced Plastics (CFRP). This non-linear modelled by fitting a strain law against experimental stress-strain curves. Inspired crystal plasticity framework, phenomenological model developed to capture matrix shearing and fibre rotation CFRP under finite strain. first verified simple shear transverse c...

We present a new approach for estimation of transmural distributions of stress and strain in the equatorial region of a passive left ventricle. We employ a thick-walled cylindrical geometry, assume that myocardium is incompressible, and use a three-dimensional constitutive relation that yields a material symmetry consistent with observed transmural variations in muscle fiber orientations. Moreo...

Angora goats are known to be vulnerable to cold stress, especially after shearing, but their thermoregulatory responses to shearing have not been measured. We recorded activity, and abdominal and subcutaneous temperatures, for 10 days pre-shearing and post-shearing, in 10 Angora goats inhabiting the succulent thicket of the Eastern Cape, South Africa, in both March (late summer) and September (...

MARCHAND and Duffy have reported detailed measurements of the temperature and strain as a shear band develops in a HY-100 steel. Assuming their torsional tests in thin-wall tubes can be adequately modeled by a viscoplastic block undergoing overall adiabatic simple shearing deformations. we investigate the effect of modeling the viscoplastic response of the material by a-power law. and flow rule...

Strain-rate effects in a unidirectional non-crimp fabric carbon/epoxy composite are addressed. To allow for kink-band formation including strain-rate and damage such composites, the paper advances recent model focused on compression loading at small off-axis angles. The is based computational homogenization with subscale represented by matrix fibre constituents finite deformation. constituent a...

Non-coaxial response refers to the deviation between directions of principal stress and plastic strain increment. In this paper, an extended hypoplastic model is proposed based on anisotropic critical state theory, describe non-coaxial sand subjected both monotonic loading rotation axis. A fabric tensor that characterizes internal structure introduced into a model, reflect effect anisotropy dil...
