Confined Granular Flow in Silos: Experimental and Numerical Investigations
ISBN: 9783319033228 / Angielski / Miękka / 2015 / 501 str. Termin realizacji zamówienia: ok. 20 dni roboczych. During confined flow of bulk solids in silos some characteristic phenomena can be created, such as: sudden and significant increase of wall stresses, different flow patterns, formation and propagation of wall and interior shear zones, fluctuation of pressures and, strong autogenous dynamic effects. These phenomena have not been described or explained in detail yet. The main intention of the experimental and theoretical research presented in this book is to explain the above mentioned phenomena in granular bulk solids and to describe them with numerical FE models...

Shear Localization in Granular Bodies with Micro-Polar Hypoplasticity
ISBN: 9783540705543 / Angielski / Twarda / 2008 / 317 str. Termin realizacji zamówienia: ok. 20 dni roboczych. This book includes a numerical investigation of shear localization in granular materials within micro-polar hypoplasticity, which was carried out during my long research stay at the Institute of Soil and Rock Mechanics at Karlsruhe University from 1985 to 1996. I dedicate my book to Prof. Gerd Gudehus from Germany, the former head of the Institute of Rock and Soil Mechanics at Karlsruhe University and the supervisor of my scientific research during my stay in Karlsruhe, who encouraged me to deal with shear localization in granular bodies within micro-polar hypoplasticity. I greatly - preciate...

Experimental and Theoretical Investigations of Steel-Fibrous Concrete
ISBN: 9783642146022 / Angielski / Twarda / 2010 / 280 str. Termin realizacji zamówienia: ok. 20 dni roboczych. This book summarizes key mechanical and physical properties of steel-fibre-added concrete and reinforced concrete. It also describes a quasi-static fracture process at meso-scale both in plain concrete and fibrous concrete using a novel discrete lattice model.

Continuous and Discontinuous Modelling of Fracture in Concrete Using FEM
ISBN: 9783642284625 / Angielski / Twarda / 2012 / 418 str. Termin realizacji zamówienia: ok. 20 dni roboczych. The book analyzes a quasi-static fracture process in concrete and reinforced concrete by means of constitutive models formulated within continuum mechanics. A continuous and discontinuous modelling approach was used. Using a continuous approach, numerical analyses were performed using a finite element method and four different enhanced continuum models: isotropic elasto-plastic, isotropic damage and anisotropic smeared crack one. The models were equipped with a characteristic length of micro-structure by means of a non-local and a second-gradient theory. So they could properly describe the...

Experimental and Theoretical Investigations of Steel-Fibrous Concrete
ISBN: 9783642422553 / Angielski / Miękka / 2014 / 280 str. Termin realizacji zamówienia: ok. 20 dni roboczych. Concrete is still the most widely used construction material since it has the lowest ratio between cost and strength as compared to other available materials. However, it has two undesirable properties, namely: low tensile strength and large brittleness that cause the collapse to occur shortly after the formation of the first crack. To improve these two negative properties and to achieve a partial substitute of conventional reinforcement, an addition of short discontinuous randomly oriented steel fibres can be practiced among others. In spite of positive properties, fibrous concrete did not...
