• Finite-element analysis of a base-isolated multi-storey steel building under seismic motions

  Publikacja

  • T. Falborski
  • R. Jankowski

  - Rok 2014

  Numerical simulation of the seismic behaviour of a multi-storey steel building, both fixed-base and base-isolated, under the 1940 El Centro earthquake was performed in this paper. The analyzed 4-storey building was decoupled from the shaking ground with the Polymeric Bearings, which can be considered a proposal of a new seismic isolation system. It consists of rectangular-shaped blocks made of a specially prepared flexible polymeric...

• Architectural and Urban Planning Solutions for the Protection of Heritage Buildings in the Context of Terrorist Attacks: Following the Example of Passive Protection Systems

  Publikacja

  • K. Grębowski
  • A. Wróbel

  - Buildings - Rok 2022

  Events in recent years showing numerous terrorist attacks raise awareness regarding the neces-sity of considering the safety of heritage buildings. The analysis of available data allows us to conclude that it is not possible to fully prevent terrorist attacks. On the other hand, it is possible to minimize the impact of such incidents through proper design of Passive Protection System (PPS) components. One possible architectural...

• Modelling of laminated glass PVB walls of buildings exposed to vehicle impact with different speeds

  Publikacja

  • K. Grębowski
  • M. Zielińska

  - ENGINEERING STRUCTURES - Rok 2023

  This paper presents an analytical model, developed for laminated glass subjected to a low-velocity impact. It has the ability to capture glass cracks as well as large non-linear deformations. It is based mathematically on the firstorder deformation concept, which considers the effect of membrane and transverse shear as well as bending. This theory uses damage mechanics to capture the glass cracking. For this purpose, several experiments...

  open access

  • S. Grymek
  • G. Rotta

  The aim of the study was to determine the biomechanical properties of the walls of the human stomach. The samples were fragments of the human stomach obtained after sleeve gastrectomy. Samples cut parallel to the stomach curves and perpendicular to the stomach curves were tested in each series. All samples were subjected to uniaxial stretching. During...

• M-integral for finite anti-plane shear of a nonlinear elastic matrix with rigid inclusions

  Publikacja

  • V. Eremeev
  • K. Naumenko

  - INTERNATIONAL JOURNAL OF ENGINEERING SCIENCE - Rok 2024

  The path-independent M-integral plays an important role in analysis of solids with inhomogeneities. However, the available applications are almost limited to linear-elastic or physically non-linear power law type materials under the assumption of infinitesimal strains. In this paper we formulate the M-integral for a class of hyperelastic solids undergoing finite anti-plane shear deformation. As an application we consider the problem...

• Reduced model of gyroscopic system

  Publikacja

  • C. Orlikowski
  • R. Hein

  - Rok 2008

  The paper presents the method of model reduction for the system with gyroscopic interactions. Two methods were used to obtain the approximate discrete models of the continuous structure: the modal decomposition method and the rigid finite element method. The first approach is used for this part of a system for which it is easy to formulate orthogonality conditions, meanwhile the second one is used for other part. The method enables...

• Curing characteristics and Mooney viscosity of reclaimed rubbers

  Dane Badawcze

  open access

  • Ł. Zedler
  • K. Formela
  • J. Ryl

  Presented data shows the difference in curing characteristics and Mooney’s viscosity between commercially available reclaimed rubbers and ground tire rubber (GTR) with specific particle size distribution cured with the same curing system and with the same manner. Samples were prepared using a two-roll mill. After 24 hours of aging at ambient conditions,...

• A simple model of circular hydraulic pump

  Publikacja

  • J. Mikielewicz
  • D. Mikielewicz

  - INTERNATIONAL JOURNAL OF HEAT AND MASS TRANSFER - Rok 2008

  Rozpatrzono warunki powstawania osiowosymetrycznego uskoku hydraulicznego. Przedstawiono model, w którym rozpatrzono obecność dodatkowych strat w równaniu Bernoulliego. Przyczyniają się one do powstawania dodatkowego wiru w miejscu uskoku. Porównanie z wynikami badań eksperymentalnych potwierdza słuszność przyjętych tez.
