The crack problem

In this paper, a smoothed weighted function with the compact support is suggested to improve the numerical accuracy of blending elements for the extended finite element method (XFEM) applied to the crack problem.

In this paper, efforts are made to develop suitable methods that can serve as the basis to detect crack location and to crack size from measured axial vibration data. This method is used to address the inverse problem of assessing the crack location and crack size in various beam structure.

The present paper addresses the problem for free vibration of multistep Timoshenko beams with arbitrary number of cracks, continuing the work accomplished in [28], where the problem was studied on the base of Euller-Bernoulli beam theory. First, the obtained general solution of uniform Timoshenko beam is employed to develop the TMM for modal analysis of multistep Timoshenko beam with multiple cracks. Then, effect of beam slenderness and stepped change in cross section on sensitivity of natural frequencies to cracks is thoroughly examined.

Reduce overall grain yield by cracking as one of the main problems directly reduced income and the availability of staple food to the farmers in the Mekong Delta. Cracking or fissuring of a grain of wheat that may occur in the rice fields by not harvested on time / practice, improper harvest and drying conditions milling operation is inappropriate. This project aims to improve the quality and value of Rice, through an integrated approach that includes farmers, millers, service providers and extension workers and educational institutions....

Reduce overall grain production and value by cracking is one of the main problems directly reduces income and the availability of staple food to the farmers in the Mekong Delta. Cracking or fissuring of a grain of wheat that may occur in the rice field by harvest time is not right / real, post-harvest conditions improper drying and milling activities inconsistent. There are a series of activities during harvesting and processing rice harvest. Figure 1 is a diagram showing a system of rice production in the Mekong Delta of Vietnam today. All strings in this system may contribute to losses.

Hacking, cracking, and cyber crimes are hot topics these days and will continue to be for the foreseeable future. However, there are steps you can take to reduce your organization's threat level. The first step is to understand what risks, threats, and vulnerabilities currently exist in your environment. The second step is to learn as much as possible about the problems so you can formulate a solid response. The third step is to intelligently deploy your selected countermeasures and safeguards to erect protections around your most mission-critical assets.
