Principles of soil deformation
, 2018 Project relevance: Once we know the stresses acting in soil mass, we can estimate the amount of deformation that soil can undergo during construction after the load application. This chapter will introduce the definitions of strain and discuss laboratory techniques used to measure soil strength and deformation.

Modelling plasticity of unsaturated soils in a thermodynamically consistent framework [PDF]
, 2009 Constitutive equations of unsaturated soils are often derived in a thermodynamically consistent framework through the use a unique 'effective' interstitial pressure. This later is naturally chosen as the space averaged interstitial pressure.

Fidelity of computational modelling of offshore jacket platforms [PDF]
, 2019 The development of oil and gas exploitation offshore has a history of about half a century. Many platforms have been built since to facilitate the production of hydrocarbons oil and gas, of which fixed offshore jacket type structures are the most ...

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance
Advanced Functional Materials, EarlyView.A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

3D numerical model in nonlinear analysis of the interaction between subsoil and SFCR slab [PDF]
, 2017 For decades attention has been paid to interaction of foundation structures and subsoil and, in turn, to development of interaction models. Complexity of a static solution is given mainly by selection of a computational model, effects of physical ...

A study of anisotropy of magnetic susceptibility of cohesive soil under unconfined compression
Shuiwen dizhi gongcheng dizhi, 2021 In recent years, the unloading of excavation engineering activities such as foundation pits and tunnels has caused excessive lateral deformation of cohesive soil, which result in more and more engineering accidents.
