Conventional materials are being replaced in the field of engineering by composite materials, due to their tailorable properties and high specific properties. These materials are extensively used in structural applications. Damping is one of the important properties of the materials used in structures, and needs to be enhanced in order to reduce structural vibrations. In the present work, the i...

Classic risk scores may underestimate the risk of cardiovascular (CV) events in specific risk groups suitable for primary prevention, such as asymptomatic hypertensive subjects. Particularly, those considered as at intermediate risk may benefit the most from a reassessment of their CV risk using novel biomarkers. In primary prevention, some imaging biomarkers, such as arterial stiffness, enhanc...

In this paper, the Two-Scale computation Method (TSM) is presented for the mechanics parameters of composite materials with small periodic configuration, including stiffness parameters and strength parameters. First the major formulation of the Two-Scale Asymptotic expressions (TSA) for composite materials with periodic configuration is briefly given. And then the two-scale computation (TSM) fo...

nonlinear static procedure (nsp) is a common technique to predict seismic demands on various building structures by subjecting a monotonically increasing horizontal loading (pushover) to the structure. therefore, the pushover analysis is an important part of each nsp. accordingly, the current paper aims at investigating the efficiencyof various algorithms of lateral load patterns applied to the...

conclusions the pattern of longitudinally increased liver stiffness measurements efficiently supported clinical decisions for individualized management strategies. repeated transient elastography in real-life clinical practice appears to have a practical role in monitoring liver transplanted patients. background liver transplanted patients need close surveillance for early signs of graft diseas...

self-centering pier (scp) has been viewed as a remarkable accomplishment which is able to sustain major lateral loading with reduced structure damage in seismic engineering. stiffness deterioration observed in experiment is vital for the seismic performance of self-centering concrete pier. in this contribution, the associated stiffness deterioration with respect to the structural damage is mode...

This paper presents an experimentally validated model for the computational analysis of metal-reinforced wooden composites. The can be used in both research and industry to effectively estimate how much a certain composite design improves bending stiffness strength hybrid component. A based on computer simulations allows prediction mechanical behaviour material consisting several interconnected...

A micromechanical finite element (FE) framework was developed to predict the viscoelastic properties (complex modulus and creep stiffness) of the asphalt mixtures. The two-dimensional (2D) microstructure of an asphalt mixture was obtained from the scanned image. In the mixture microstructure, irregular aggregates and sand mastic were divided into different subdomains. The FE mesh was generated ...

AIMS Thoracic aortic aneurysm (TAA) is potentially life-threatening and requires close follow-up to prevent aortic dissection. Aortic stiffness and size are considered to be coupled. Regional aortic stiffness in patients with TAA is unknown. We aimed to evaluate coupling between regional pulse wave velocity (PWV), a marker of vascular stiffness, and aortic diameter in TAA patients. METHODS In...

In this paper, an analytical formula to calculate the radial stiffness of groove elastic support is presented. The influence of structure parameters on radial stiffness and homogeneity of radial stiffness is investigated as well. The accuracy and calculating speed of the analysis formula are compared to that of finite element method (FEM). Findings are as following: The calculating speed of ana...
