Original scientific paper This paper presents the S-N approach to fatigue failure analysis of welded joints that integrates well with finite element modelling. Goodman's criterion and fatigue criterion based on the equivalent stress range were used for the analysis of the fatigue failure. Goodman's criterion and fatigue criterion based on the equivalent stress range, for determining fatigue saf...

in this paper we focus on a continuously deteriorating two units series equipment which its failure can not be measured by cost criterion. for these types of systems avoiding failure during the actual operation of the system is extremely important. in this paper we determine inspection periods and maintenance policy in such a way that failure probability is limited to a pre-specified value and ...

In this paper, we focus on a continuously deteriorating critical equipment which its failure cannot be measured by cost criterion. For these types of systems like military systems, nuclear systems, etc it is extremely important to avoid failure during the actual operation of the system. In this paper we propose an approach which constrains failure probability to a pre-specified value. This valu...

OBJECTIVE To compare surgical outcomes between the first and second operated eyes in patients who underwent trabeculectomy in both eyes. METHODS This retrospective clinical cohort study at five clinical centers in Japan included 84 patients with open-angle glaucoma who underwent primary trabeculectomy in both eyes. The primary outcome was surgical success or failure, with failure being define...

In this paper, a generic methodology based on swarm algorithms using Artificial Bee Colony (ABC) algorithm is proposed for combined cost and weight optimization of laminated composite structures. Two approaches, namely Vector Evaluated Design Optimization (VEDO) and Objective Switching Design Optimization (OSDO), have been used for solving constrained multi-objective optimization problems. The ...

This paper includes the most important findings of a series of linear analyses focusing on the development of failure that is identified through different failure criteria. The historic monument which was selected for this investigation is the church of Agia Triada, in the District of Karditsa, Greece. The numerical simulation for the church of Agia Triada includes all parts of the super-struct...

This paper deals with the development of a numerical simulation methodology for estimating damages in laminate composite materials caused by a low-speed impact. Experimental tests were performed on laminate plates reinforced with woven carbon fibers and epoxy resin. Three thickness plates were evaluated. The impact loads were transversal and punctual. Two lamina failure criteria were evaluated....

nurses. One such criterion was that patients with heart failure, who are receiving more than frusemide 40mg, should also be receiving an ACE inhibitor. The audit consisted of 502 patients from 10 practices who were receiving diuretics. Of those patients who satisfied our agreed criterion for ACE inhibitors, 50% were receiving treatment that complied with the criterion. These are early days for ...

Methods of damage development analyses for various types of composite materials such as 3-D woven composite have not been established sufficiently because it is quite difficult to simulate the failure propagation. A FEM simulation of failure process of 3-D composite was executed by Mibayashi including the thermal residual stresses after the curing process, and the deformations and stresses calc...
