This paper aims to propose methods to mitigate the risks of flash flood events in arid rural communities with poor infrastructure. A flash flood management case study was conducted at Afouna Village in Egypt, which is characterized by an arid climate and faced a devasting flash flood in 2015. First, the flash flood was modelled and it was...

Airborne wind energy (AWE) is an innovative renewable energy technology, with the potential to substantially reduce the cost of energy. This paper introduces a solution for one of the main challenges of AWE systems, which is the automated reliable launching of the airborne system component. Our launch system configuration consists of a rigid...

Massive improvements in the thermophysical properties of nanofluids over conventional fluids have led to the rapid evolution of using multiwalled carbon nanotubes (MWCNTs) and graphene nanoplatelets (GNPs) in the field of heat transfer. In this study, the heat transfer and entropy generation abilities of MWCNTs/GNPs hybrid nanofluids were...

The failure probability of geotechnical structures with spatially varying soil properties is generally computed using Monte Carlo simulation (MCS) methodology. This approach is well known to be very time-consuming when dealing with small failure probabilities. One alternative to MCS is the subset simulation approach. This approach was mainly...

During the breakup of continents in magmatic settings, the extension of the rift valley is commonly assumed to initially occur by border faulting and progressively migrate in space and time toward the spreading axis. Magmatic processes near the rift flanks are commonly ignored. We present phase velocity maps of the crust and uppermost mantle of...

In order to arrive at safe and reliable design of composite structures, understanding of the mechanisms and mechanics of damage growth in these materials is of paramount significance. Numerical models, if designed, implemented and used carefully, can be helpful not only to understand the mechanisms and mechanics of damage growth but also to...

Experimental testing and numerical analysis often travel in tandem in a design process. Recent advances in novel numerical techniques to simulate mesh objective crack propagation offer a great potential for accurate and efficient damage analysis of composite laminates. This paper presents a numerical study on computational modeling of mesh...

Numerical analysis of progressive damage in fiber-reinforced laminated composite plates is a challenge due to the presence of different, complex failure mechanisms and their mutual interaction. A meso-scopic progressive failure model is presented to simulate interacting damage mechanisms (matrix cracking and delamination) in laminated composite...

A finite element model based on solid-like shell elements is presented for the simulation of progressive damage in laminated composite structures. To model mesh independent matrix cracking, a discontinuous solid-like shell element (DSLS) is utilized. The shell element has only displacement degrees of freedom, thus avoids the need for a...
