Improved surgical procedures and implant developments for ligament or tendon repair require an in-depth understanding of tissue load-deformation fatigue properties. Cyclic testing will provide crucial information on the behavior these materials under reoccurring loads strength. Sparse data are available describing soft cyclic loading. To examine strength, a new technology was trialed deploying ...

the crankshaft is one of the most critically loaded components as it experiences cyclic loads in the form of bending and torsion during its service life. its failure will cause serious damage to the engine so it’s important at the time of design to verify fatigue strength. more challenges in crankshaft design due to increasing vehicle payloads, lower weight requirement, higher efficiency and lo...

We consider an inverse problem for determining an inhomogeneity in a viscoelastic body of the Zener type, using Cauchy boundary data, under cyclic loads at low frequency. We show that the inverse problem reduces to the one for the Helmholtz equation and to the same nonlinear Calderon equation given for the harmonic case. A method of solution is proposed which consists in two steps : solution of...

The introduction of high molecular weight poly(methyI methacrylate) or poly(butadiene-co-acrylonitrile) into ethyl 2-cyanoacrylate produced viscous adhesives with a homogeneous or heterogeneous structure after cure. Steel joints bonded with these adhesives are shown to have improved tensile shear strength, deformability and stress relaxation of bonds compared with pure cyanoacrylate adhesive. P...

This paper presents the results of study composite beam elements under action cyclic loads. The experimental demonstrated that with a decrease in level applied load, its frequency unchanged, “viability” beams increased (the number cycles before collapse); effects, shear deformations and contact openings are characterized by nonlinear functions.

The seismic behaviour of reinforced concrete structures built with plain reinforcing bars is sometimes conditioned by the slippage between and surrounding in elements as exterior beam-column joints. anchorage beam core joint weak confinement, inappropriate reinforcement detailing for loads poor bond properties are common reasons collapse many structures. This paper presents results four unidire...

The article presents the results of experimental studies carrier ability, longitudinal and transverse deformations reinforced concrete columns, clips made fiber-reinforced plastics, with a few repeated loads. Dependences residual strength after cyclic compressive forces are obtained. Are given suggestions for acceptable deformation values as well proposals calculation design.

β-NiAl coatings on a superalloy substrate will inevitably result in severe rumpling at elevated temperatures; however, the associated mechanisms are not completely understood. The scale behavior of β-NiAlHf coating deposited by electron beam physical vapor deposition (EB-PVD) single crystal IC21 was investigated this work. Some internal factors, including mismatch coefficient thermal expansion ...

The analysis of the normative document DSTU B В.2.6210: 2016 on assessment technical condition steel building structures, which are in operation. In particular, does not address degradation processes. Does consider monitoring impacts and loads. calculation structures for cyclic crack resistance, resistance to brittle fracture. definition a residual resource. issues reasonable reassignment exte...
