Un modelo monodimensional para el análisis de barras de pared delgada de material compuesto

Author(s): Forces A. , JGarrido , J.A. , Vassallo , A.
Description: One–dimensional model is presented for the analysis of thin–walled composite beams. Each wall is made of orthotropic layers bonded together to form a laminate that can be anisotropic. The theory uses the Navier–Bernoulli and Vlasov models to describe bending and twist, respectively, at beam level, a...

Hardening effects on formability limit prediction based on Gurson-type damage models and bifurcation analysis

Description: In this work, ductility limits of metallic materials, associated with the occurrence of strain localization, are predicted using the GTN damage model coupled with bifurcation theory. The resulting approach is implemented into the finite element code ABAQUS within the framework of large plastic strai...

Interpolación mínimo-cuadrática de superficies a partir de datos irregularmente distribuidos

Description: La interpolación de superficies a partir de datos irregularmente distribuidos se ha basado normalmente en algoritmos tales que 1a.superficie obtenida pasa por todos los puntos base de interpolación. Sin embargo, cuando dichos datos son experimentales, su grado de fiabilidad no tiene por qué ser el m...

Rotation effect on peristaltic transport of a Jeffrey fluid in an asymmetric channel with gravity field

Description: In this paper, the peristaltic flow of a Jeffrey fluid in an asymmetric rotating channel is studied under long wavelength and low Reynolds number assumptions are investigated. Closed form expressions for the pressure gradient, pressure rise, stream function, axial velocity and shear stress on the ch...

Determination of loop length, tightness factor and porosity of single jersey knitted fabric

Description: After fabric relaxation, there is a reduction in wale and course density due to a reduction in loop length and this actually will affect the fabric properties. Then, it is useful to find a relation between loop length and courses and wales per unit length as well as the yarn thickness because wales ...

Effect of intravenous infusion of iodinated contrast media on the coronary blood flow in dogs

Description: Coronary computed tomography angiography (CCTA) is obtained using peripheral intravenous iodinated contrast agents (ICA) injection. There is continuing attempts to derive coronary physiological information like coronary blood flow (CBF) and/or fractional flow reserve from CCTA images. However, no da...

Is LigaSure a safe cystic duct sealer? An ex vivo study

Description: To compare the efficacy and safety of both mechanical methods (clips) and electrosurgical instruments, harmonic scalpel (HS) and LigaSure (LS), for securing the cystic duct during laparoscopic cholecystectomy (LC). During the study period from October 2010 to October 2012, 458 patients with gallblad...

Sub-acute Ruminal Acidosis (SARA) and its Consequence in Dairy Cattle: A Review of Past and Recent Research at Global Prospective

Author(s): Nejash Abdela
Description: Dairy producer increase milk production by over feeding grain diets that are high in starch and low in fiber to increase intake of energy and met dietary requirements of the high yielding dairy cows. However, these diets increase the risk of subacute ruminal acidosis (SARA). Thus, maximizing milk pr...
