The mixed boundary problems for finite plates with one crack or two collinear cracks are studied. Complex stress functions that satisfy the equilibrium equations and compatibility conditions in the cracked plate as well as the stress condition on crack surfaces are presented. Four models, that is, a square plate with one crack or with two collinear cracks …
DetailsA contractors license issued from the Arkansas Contractors Licensing Board is required for any work with a total job cost $2000 and up for all residential or commercial work on new and existing buildings. Siff's Custom Tile & Flooring Inc currently holds license 0278440324, 0278440323, 0278440322, 0278440821, 0278440820, 0278440819, …
DetailsThe hierarchy of controls became the gold standard for reducing SIFs in workplaces. After all, if you can eliminate a hazard (and new hazards rarely arise), most injuries and fatalities can be eliminated through rigorous and reliable engineering controls. While the hierarchy of controls went a long way towards dramatically improving safety in ...
DetailsSIFFS is the apex body of organisations of small-scale artisanal fish workers. It has a three-tier organisational structure. With over 9104 member fishermen, organised through 153 primary societies in eight districts of Southern peninsular India, SIFFS over the last two decades has kept its focus on strengthening the artisanal fisheries.
DetailsSIFFS is a non-governmental organization working in the marine fisheries sector. It is the apex body of organizations of small-scale artisan fish workers. With over 6,000 member fishermen, organised through 100 primary societies in eight districts of Southern peninsular India, SIFFS over the last two decades has kept its focus on strengthening ...
Details1. Introduction. Riveted stiffened panel is the elementary part and widely used in aircraft structures, for example fuselage and wing, due to its high buckling load, inherent fail-safe, and damage tolerant capability [1].There are numerous rivet holes in the same aircraft structure suffering from similar fatigue load.
DetailsThe original impetus came in 1983, when SIFFS took up the boat building programme. Research and Development in several aspects of artisanal fisheries has been one of the major concerns of SIFFS shortly after its inception in 1980. While fish marketing, credit and support to member societies were the most important issues around which SIFFS was …

DetailsHSIF = High-Energy Serious Injury or Fatality. Capacity = Incident with a release of high energy in the presence of a direct control where a serious injury is not sustained. PSIF = Potential Serious Injury or Fatality – Incident with a release of high energy in the absence of a direct control but a serious injury was not sustained.
DetailsOne basic idea of SIF prevention is to focus attention on the importance of effective controls around high-risk activities. Controls are: Acts, or actions that must be taken. Objects, or devices that work when needed without acts. Systems, or combinations of …
DetailsThis paper presents a 2D numerical technique based on the boundary element method (BEM) for the analysis of linear elastic fracture mechanics (LEFM) problems on stress intensity factors (SIFs) involving anisotropic bimaterials. The most outstanding feature of this analysis is that it is a singledomain method, yet it is very accurate, efficient, …
DetailsAs considered carbon-free, the use of nuclear energy for thermal energy generation may expand in the future, with the guarantee of safe operation of the nuclear reactor. In a nuclear reactor pressure vessel (RPV), the nozzle area is an important part of the safe operation. It bears internal pressure, axial force, and overall moment, and at the …
