Abstract The understanding of the weakening mechanism tensile strength rock subjected to cyclic wetting-drying is critical for engineering. Tensile tests were conducted on a total 35 sandstone specimens with different cycles. crack propagation process and acoustic emission characteristics tested samples obtained through high-speed camera system. results indicate that observably reduced after we...

In the context of inspection and maintenance actions for beach walkways in North Portugal, some samples wood used their construction were collected – <em>Pinus</em> <em>sylvestris</em> wood, widely applied country. The sustainability over natural coastal areas is very dependent on material durability. One main problems timber to build those structures its behavior under ...

The effects of a sulfonated oil (SO) stabiliser on the swell–shrink properties an expansive soil were investigated through cyclic wetting–drying tests. action led to reconstruction microstructure by inducing clay particle aggregation. Accordingly, greater number applied cycles, lower potential up fourth cycle, beyond which swelling and shrinkage strains attained elastic equilibrium. At any give...

The present paper demonstrates how a natural crack mosaic resembling random tessellation evolves with repeated 'wetting followed by drying' cycles. system here is network in drying colloidal material, for example, layer of mud. A spring model used to simulate consecutive wetting and cycles mud layers until the matures. simulated results compare favourably reported experimental findings. evoluti...

The strength and deformation properties of tailing materials are strongly affected by their hydromechanical history including the cycles desiccation re-saturation they undergo due to often layered deposition process. current study reviews fundamental characteristics some commonly used constitutive models for partially saturated soils, namely Barcelona Basic Model (BBM), Glasgow Coupled (GCM), a...

This paper proposes a wetting and drying treatment for the piecewise linear Runge–Kutta discontinuous Galerkin approximation to the shallow water equations. The method takes a fixed mesh approach as opposed to mesh adaptation techniques and applies a post-processing operator to ensure the positivity of the mean water depth within each finite element. In addition, special treatments are applied ...
