the testing equipment and the methods of field tests used for calculating the modulus of deformation and elasticity of the shah _ abass dam foundation rock are described here. the communication includes conclusions of which a sharp difference between the quality of the roc kin the right and in the left bank is the most important.

One of the parameters that has been identified as influencing the structural response of buildings is the dynamic Modulus of Elasticity of masonry units. The first aim of this paper is to experimentally investigate the use of high frequency sinusoidal loading to determine the dynamic Modulus of Elasticity of masonry units. The Longitudinal Vibration and the Ultrasonic Pulse methods were origina...

Average stress during shear bond testing, and deformation behaviour during nano-indentation testing were calculated for the bonding area as a bonding site for copolymerization with resin composite in dentine bonding systems. First average stress was calculated in the bonding area between bovine dentine and composite resin. Secondly, the plastic deformation zone size was calculated using an elas...

OBJECTIVE To define the modulus of elasticity for nasal septum, auricular, upper lateral, and lower lateral cartilages. METHODS Prospective enrollment of sequential patients undergoing septorhinoplasty. Test samples were obtained through routine surgical interventions using atraumatic harvesting techniques. The modulus of elasticity was determined using a customized biomechanical testing devi...

this study was carried out to determine the effect of seed growing regions and loading speed on some mechanical properties of castor seed. these properties are used to design and improve related machines such as expeller that are used for extraction of oil from castor seed. mechanical properties of castor seed were expressed in terms of rupture force and energy, bio-yield force, apparent modulu...

Complex cloud services rely on various IaaS, PaaS, and SaaS cloud offerings. Fast (re)deployment and testing cycles, and the rapidity of changes of various dependent infrastructures and services, imply a need for continuous adaptation. Although software-based elasticity control solutions can automate various decisions through intelligent decisionmaking processes, in many cases, such adaptation ...

This paper is concerned with the numerical simulation of the interaction of compressible viscous flow with elastic structures. The flow is described by the compressible Navier-Stokes equations written in the arbitrary Lagrangian-Eulerian (ALE) form. For the elastic deformation we use 2D linear elasticity and nonlinear St. Venant-Kirchhoff and neo-Hookean models. The discretization of both flow ...

The importance of mesenchymal stem cells (MSC) in vascular regeneration is becoming increasingly recognized. However, few in vitro studies have been performed to identify the effects of environmental elasticity on the differentiation of MSC into vascular cell types. Electrospinning and photopolymerization techniques were used to fabricate a three-dimensional (3-D) polyethylene glycol dimethacry...
