• Numerical Modelling of Structures with Uncertainties

  Publikacja

  • M. Kahsin

  - Polish Maritime Research - Rok 2017

  The nature of environmental interactions, as well as large dimensions and complex structure of marine offshore objects, make designing, building and operation of these objects a great challenge. This is the reason why a vast majority of investment cases of this type include structural analysis, performed using scaled laboratory models and complemented by extended computer simulations. The present paper focuses on FEM modelling...

  The paper presents experiences gained during work with numerical model of Geo Metro vehicle used for simulations of crash tests with road safety barriers. Attention is drawn to the subject of tire/wheel breakage during collision events. Some methods for improvement of the model are presented in the paper. Several results for the normative vehicle numerical tests are introduced. Simulations were carried out using LS-DYNA finite...

  - Studia Geotechnica et Mechanica - Rok 2006

  Analiza numeryczna badania DMT wykonanego w komorze kalibracyjnej w Katedrze Geotechniki Politechniki Gdańskiej. Badania przeprowadzono w piasku Lubiatowo średnio zagęszczonym i zagęszczonym przy składowej pionowej naprężenia 100 kPa. Modelowano proces wciskania ostrza dylatometru oraz fazę odkształcenia membrany. Analiza parametryczna uwzględnia wpływ wartości kąta tarcia wewnętrznego i dylatancji oraz modułu odkształcenia uzyskanych...

  • R. Kędra

  - Prace Studentów Politechniki Wrocławskiej. Seria : Konferencje - Rok 2015

  The article presents application of finite difference method to damage detection and its size evaluation in concrete structure by elastic wave propagation method. The simulations of wave propagation in concrete structure were performed for six different damage scenarios. Damages were modelled as areas with changed material properties. Investigation focused on the influence of damage size on the energy of wave reflection. Presented...

• EXPERIMENTAL AND NUMERICAL VALIDATION OF THE IMPROVED VORTEX METHOD APPLIED TO CP745 MARINE PROPELLER MODEL

  Publikacja

  • P. Król
  • K. Tesch

  - Polish Maritime Research - Rok 2018

  The article presents a numerical analysis of the CP745 marine propeller model by means of the improved vortex method and CFD simulations. Both numerical approaches are validated experimentally by comparing with open water characteristics of the propeller. The introduced modification of the vortex method couples the lifting surface approach for the propeller blades and the boundary element method for the hub. What is more, a...

  - Rok 2017

  A proposition of some numerical modelling of the 3D printout is presented in the paper. The proposed model is composed of some 1D elements. The resulting numerical model of the infill consist of beam, spring and rigid elements. Obtained results confirm correctness of the proposed modelling method. Two methods of estimation of the spring parameters are proposed in the paper. In the first method, mechanical properties of the connecting...
