  • Smooth Particle Hydrodynamics (SPH) approach in simulating large penetration into soil

    Publication

    - Year 2012

    A study of Smooth Particle Hydrodynamics (SPH) approach for predicting large soil deformation is presented. Theoretical basics of SPH method, including the equations governing, discussion of the importance of smoothing function length, contact formulation, boundary treatment and finally utilization in hydrocodes simulations are presented. An application of SPH to a real case of large penetrations (crater creating) into soil caused...

  • NUMERICAL SIMULATION OF CRATER CREATING PROCESS IN DYNAMIC REPLACEMENT METHOD BY SMOOTH PARTICLE HYDRODYNAMICS

    A theoretical base of SPH method, including the governing equations, discussion of importance of the smoothing function length, contact formulation, boundary treatment and finally utilization in hydrocode simulations are presented. An application of SPH to a real case of large penetrations (crater creating) into the soil caused by falling mass in Dynamic Replacement Method is discussed. An influence of particles spacing on method...

  • Metoda SPH+MES na przykładzie symulacji wzmocnienia podłoża gruntowego metodą wymiany dynamicznej

    Publication

    - Year 2016

    Praca zawiera opis hybrydowej metody połączenia metody bezsiatkowej Smooth Particle Hydrodynamics (SPH) z Metodą Elementów. Metoda SPH ma zastosowania w zagadnieniach w których występują skomplikowane i zmienne w czasie algorytmy kontaktowe co pozwoliło na jej wykorzystanie w symulacji formowania kolumny przez wbijanie i rozpychanie materiału zasypowego. Przedstawiono wskazówki do przygotowania symulacji numerycznej z wykorzystaniem...

  • Numerical solutions for large deformation problems in geotechnical engineering

    Publication

    - Year 2014

    The problem of large deformations often occurs in geotechnical engineering. Numerical modeling of such issues is usually complex and tricky. The chosen solution has to implicate soil-soil and soil-structure interactions. In this paper, a review of the most popular numerical methods for large deformation problems is presented. The Coupled Eulerian-Lagrangian (CEL) method, the Arbitrary Lagrangian-Eulerian (ALE) method, the Smoothed...
