Thermo‐hydro‐mechanical analysis of partially saturated porous materialsPresents a fully coupled numerical model to simulate the slow transient phenomena involving heat and mass transfer in deforming partially saturated porous materials. Makes use of the modified effective stress concept together with the capillary pressure relationship. Examines phase changes (evaporation‐condensation(, heat transfer through conduction and convection, as well as latent heat t... ...

A linear complexity intersection algorithm for discrete element simulation of arbitrary geometriesWe present an algorithm for contact resolution that is valid for a wide variety of polygonal two dimensional shapes and is of linear computational complexity. The algorithm is designed for use in discrete element analysis of granular and multibody systems exhibiting discontinuous behaviour. Contact detection usually consists of a spatial sorting phase and a contact resolution phase. The sp... ...

An anisotropic elastoplastic model based on an isotropic formulationThis paper shows a generalization of the classic isotropic plasticity
theory to be applied to orthotropic or anisotropic materials. This approach
assumes the existence of a real anisotropic space, and other fictitious
isotropic space where a mapped fictitious problem is solved. Both spaces are
related by means of a linear transformation using a fourth order
transformation tensor that conta... ...

THE DISCRETE ELEMENT METHOD FOR ANALYSIS OF FRAGMENTATION OF DISCONTINUAThis paper is concerned with the determination of the transient stress and deformational state of plate‐like discontinua subject to flexural cracking. Such a phenomenon can be easily visualized as the type of fragmentation to floating sea ice impacted by an ice‐breaker or offshore platform. The discrete element method is used to solve the dynamic equilibrium equations for each distinct def... ...

Implementation and application of elastodynamic boundary element discretizations with improved stability propertiesDirect and indirect time marching boundary element methods often become numerically unstable. Evidence of, and reasons for, these instabilities is provided in this paper. Two new time stepping schemes are presented, both of which are more stable than the existing standard schemes available. In particular, we introduce the Half‐step scheme, which is more accurate and far more stable than ex... ...

Numerical algorithms for solving shallow water hydro-sediment-morphodynamic equationsPurpose The purpose of this paper is to present a fully conservative numerical algorithm for solving the coupled shallow water hydro-sediment-morphodynamic equations governing fluvial processes, and also to clarify the performance of a conventional algorithm, which redistributes the variable water-sediment mixture density...

Pollution‐free energy production by a proper misuse of finite element analysisNotes that what applied scientists in classical continuum mechanics are doing is based on knowledge established by Newton, Cauchy, Euler, Rayleigh and others, and no really fundamental laws or principles in continuum mechanics have been “discovered” since. Newtonian mechanics provides a vital tool, which is still valid in all manners of ways from engineering to astronomy. Illustrates that ... ...
