Overshooting of Hypoplastic Models With Intergranular Strain: Manifestation, Implications and Remedy
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Intergranular strain extensions of hypoplasticity (IGS, ISA, GIS) are widely used to model small‐strain and cyclic soil behaviour. However, recent studies and our own simulations reveal that these models can exhibit stress overshooting not only under repeated small loading cycles but also during monotonic loading.

, 2009 In the Campania region the pyroclastic soils resting on the limestone massif are often affected by mudflows. These landslides involve more superficial deposits, products of the volcanic eruption of the districts: Campi Flegrei and Somma Vesuvius.

Use of a genetic algorithm to perform reliability analysis of unsaturated soil slopes
, 2009 Rainfall induced landslides are a major cause of disturbance to transport networks in many parts of the world. In slopes where the water table is some depth below the ground surface, negative pore water pressure (suctions) develop in the near surface ...

Vadose Zone Journal, 2018 In geotechnical engineering practice, many projects such as stability analysis of slopes or trenches and pavement design involve soils in vadose zones at shallow depths, where soils are under unsaturated conditions. For these types of projects, undrained

Near Surface Geophysics, EarlyView.Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.

The Role of Material Structure in Compacted Earthen Building Materials: Implications for Design and Construction [PDF]
, 2011 Rammed earth is an earthen construction material and an ancient construction technique. It is formed by compacting layers of moist sandy loam subsoil into formwork which is then removed, exposing the material and creating a freestanding, monolithic ...

Polymer International, EarlyView.The 100% recycling of optimal polycarbonate/acrylonitrile–butadiene–styrene/poly(methyl methacrylate) (PC/ABS/PMMA) blends, identified through the mixture design, over multiple successive cycles provides valuable insights into their life cycle. Subsequently, chemical, rheological, thermal and mechanical characterizations will be carried out to evaluate

The Recovery of Soils after Compaction: A laboratory investigation into the effect of wet/dry cycles on bulk density and soil hydraulic functions [PDF]
, 2009 Van den Akker et al. (2003) stated that “European subsoils are more threatened than ever in history” in an editorial referring to the results of the European Union concerted action “Experiences with the impact of subsoil compaction on soil crop growth ...
