Modeling of wood frame structures with different insulation materials under damaging dynamic loading
PublicationWood frame buildings are very popular in regions that are exposed to different dynamic excitations, such as damaging earthquakes. Their seismic resistance is really important in order to prevent structural damages and human losses. This paper presents the results of advanced numerical investigation carried out using the FEM. Based on the models of wall panels, the numerical model of real structure of the wood frame building has...

On possible applications of media described by fractional-order models in electromagnetic cloaking
PublicationThe purpose of this paper is to open a scientific discussion on possible applications of media described by fractional-order (FO) models (FOMs) in electromagnetic cloaking. A 2-D cloak based on active sources and the surface equivalence theorem is simulated. It employs a medium described by FOM in communication with sources cancelling the scattered field. A perfect electromagnetic active cloak is thereby demonstrated with the use...

Zastosowanie metody estymacji rozkładem dyskretnym do oceny niezawodności fundamentu
PublicationPraca dotyczy oceny nośności granicznej stochastycznego podłoża gruntowego. Przyjmując jako miarę bezpieczeństwa wskaźnik niezawodności, analizę przeprowadzono metodą estymacji rozkładem dyskretnym (PEM - Point Estimate Method). W metodzie tej ciągłą zmienną losową zastępuje się składającą się z impulsów dyskretną zmienną losową i aproksymuje charakterystyki statystyczne. Obliczenia wykonano dla przypadku obciążonej pionowo i osiowo...

Rola geosiatek Tensar przy wzmacnianiu słabych podłoży gruntowych pod nawierzchniami ulepszonymi
PublicationKiedy konstrukcje nawierzchni projektuje się na słabych gruntach, wzmocnienia przy użyciu geosiatek są jedną z najlepszych opcji.Za krytyczną wartość wskaźnika nośności podłoża gruntowego uznaje się najczęściej CBR <2,5. Katalogo typowych nawierzchni [1,2] zalecają jednak zastosowanie geosyntetyków nawet dla podłoży grupy nośności G3 i G4 (przy CBR <5) w celu uzyskania bardziej efektywnego ekonomicznie rozwiązania. Jeżeli geosiatki...

On Nonlinear Bending Study of a Piezo-Flexomagnetic Nanobeam Based on an Analytical-Numerical Solution
PublicationAmong various magneto-elastic phenomena, flexomagnetic (FM) coupling can be defined as a dependence between strain gradient and magnetic polarization and, contrariwise, elastic strain and magnetic field gradient. This feature is a higher-order one than piezomagnetic, which is the magnetic response to strain. At the nanoscale, where large strain gradients are expected, the FM effect is significant and could be even dominant. In...

Analiza rozkładu prądu w celce do pomiaru parametrów elektrycznych - mode lMES.
PublicationPrzedstawiono analizę rozkładu prądu w celce do pomiarów elektrycznych parametrów próbki zęba. Próbka taka charakteryzuje się małymi rozmiarami i skrajnymi wartościami parametrów elektrycznych. Czyni to pomiar jej parametrów szczególnie trudnym. Analiza została przeprowadzona za pomocą metody elementów skończonych (MES). Wykazano, że nawet połowa prądu może przepływać poza próbką. Uzyskane wyniki silnie zależą od relacji...
