We study the creep rupture of fiber composites in the framework of fiber bundle models. Two fiber bundle models are introduced based on different microscopic mechanisms responsible for the macroscopic creep behavior. Analytical and numerical calculations show that above a critical load the deformation of the creeping system monotonically increases in time resulting in global failure at a finite...

Scalability becomes the basic need for distributed systems. With the increase of users, load on application servers also keep increasing. This requires a critical action to balance the load on servers. Load balancing is the concept of balancing load on servers using various load balancing techniques. In this paper we discuss various load-balancing techniques that are currently available. We dis...

Abstract. The strength and stability properties of hierarchical load bearing networks and their strengthened variants have been discussed in recent work. Here, we study the avalanche time distributions on these load bearing networks. The avalanche time distributions of the V− lattice, a unique realization of the networks, show power-law behavior when tested with certain fractions of its trunk w...

Fracture assessment of U- and V-notches is important in mechanical engineering. One can use the J-integral as fracture parameter in order to predict the critical fracture load in notches. The critical value of the J-integral in cracks is a function of the material properties. In notches, however, the material properties as well as the notch dimensions affect this critical value (named fracture ...

the current study presents a new analytical method for buckling analysis of rectangular and annular beams made up of functionally graded materials with constant thickness and poisson’s ratio. the boundary conditions of the beam are assumed to be simply supported and clamped. the stability equations were obtained by using conservation of energy. the critical buckling load and first mode shape we...

Analytical relations between the critical buckling load of a functionally graded material (FGM) Timoshenko beam and that of the corresponding homogeneous Euler–Bernoulli beam subjected to axial compressive load have been derived for clamped–clamped (C–C), simply supported–simply supported (S–S) and clamped–free (C–F) edges. However, no such relation is found for clamped–simply supported (C–S) b...

Color is a critical part of objects representation as well as critical cue for recognizing objects. However, it is less clear how people represent color in memory. The present study aimed at investigating this issue. We designed a procedure based on short-term sensory memory load procedure mixed with a color-priming paradigm. Participants learned three visual stimuli (either non-words – lexical...
