Mechanical signal is important for regulating cellular activities, including proliferation, metabolism, matrix production, and orientation. Bioreactors with loading functions can be used to precondition cells in three-dimensional (3D) constructs so as to study the cellular responses to mechanical stimulation. However, full-scale bioreactor is not always an affordable option considering the high...

In this Report factors affecting the accuracy of Miner's Rule are dls-cussed. An nvestlgation 1s also described of the cumulative damage behaviour of DID 5014 alumlnlun alloy lug specuwns using random loading. It 1s concluded that the devlatlons from Miner's Rule observed in the uxestlgation can be ascribed manly to the actlon of residual stresses associated with yielding at tllf point of fatzg...

The physical basis of computationally tractable models of crystalline plasticity is reviewed. A statistical mechanical model of dislocation motion through forest dislocations is formulated. Following Franciosi and co-workers, the strength of the short-range obstacles introduced by the forest dislocations is allowed to depend of the mode of interaction. The kinetic equations governing dislocatio...

Recently, De Martino et al. [J. Stat. Mech. (2009) P08023; Phys. Rev. E 79, 015101 (2009)] have presented a general framework for the study of transportation phenomena on random networks with annealed disorder. One of their most significant achievements was a deeper understanding of the phase transition from the uncongested to the congested phase at a critical traffic load on uncorrelated netwo...

Recent advances in flash memory technology have reduced the cost-per-bit of flash storage devices, thereby enabling the development of large-capacity SSDs. However, two major concerns arise in designing SSDs. The first is the poor performance of random writes, and the second is the large size of the internal DRAM of an SSD. Although the previously proposed demand map loading technique can reduc...

A generalized model has been developed for the prediction of pressure drop and flooding in packed columns in which gas and liquid flow countercurrently. The model has been validated for a wide variety of packings, both random and structured. A single mathematical expression is used to describe all flow regimes: dry gas, irrigated gas flow below the load point, loading region, and flooding. The ...

The present paper offers a meso-scale numerical model to investigate the effects of random distribution of aggregate particles and steel fibers on the elastic modulus of Steel Fiber Reinforced Concrete (SFRC). Meso-scale model distinctively models coarse aggregate, cementitious mortar, and Interfacial Transition Zone (ITZ) between aggregate, mortar, and steel fibers with their respective materi...

this study aims to numerically investigate on the crashworthiness of thin-walled square tubes by consideration of 3-d oblique loading. in this type of loading, direction of loading is defined by using two spatial angles relative to the position of the tube. to this aim, finite element (fe) analysis is employed to simulate the loading for 8 different numerical models with different loading orien...
