Large-Scale Fatigue Testing Based on the Rotating Beam Method
نویسندگان
چکیده
Abstract A large-scale fatigue testing machine based on the rotating beam method in a four-point bending configuration was designed and built. With device, high-strength metal specimens with 32-mm gauge diameter 100-mm length can be tested at cyclic frequency of up to 48 Hz. In this work, particular attention paid evaluating spatial temporal uniformity loading within large specimen; methods for quantitative evaluation these effects were developed. The developed test methodology allows size, microstructure, surface conditions that are similar actual parts.

On the Corotational Beam Element Formulation in Large Deformation Analysis
This paper sheds more light on the co-rotational element formulation for beams with uniform cross-section. The co-rotational elements are commonly used in problems in which a structure undergoes a large deformation. In this study, the foregoing element obeys the Euler-Bernoulli beam assumptions. Unlike the formulations presented in the literature, in this paper, a number of local nodal coordina...
متن کاملLarge-scale features of rotating forced turbulence.
Large-scale features of a randomly isotropically forced incompressible and unbounded rotating fluid are examined in perturbation theory. At first order in both the random force amplitude and the angular velocity, we find two types of modifications to the fluid equation of motion. The first correction transforms the molecular shear viscosity into a (rotation independent) effective viscosity. The...
متن کاملDeveloping a New Method in Object Based Classification to Updating Large Scale Maps with Emphasis on Building Feature
According to the cities expansion, updating urban maps for urban planning is important and its effectiveness is depend on the information extraction / change detection accuracy. Information extraction methods are divided into two groups, including Pixel-Based (PB) and Object-Based (OB). OB analysis has overcome the limitations of PB analysis (producing salt-pepper results and features with hole...

متن کاملA partition-based algorithm for clustering large-scale software systems
Clustering techniques are used to extract the structure of software for understanding, maintaining, and refactoring. In the literature, most of the proposed approaches for software clustering are divided into hierarchical algorithms and search-based techniques. In the former, clustering is a process of merging (splitting) similar (non-similar) clusters. These techniques suffered from the drawba...
