Journal ArticleDOI
Modelling, and characterization of 3D printed cellular structures
TL;DR: In this article, a procedure for characterizing the deformation process of a regular cellular structure under static loading conditions is presented, where three different topologies with similar relative densities were designed and fabricated by fused deposition modeling of ABSplus material.
Journal ArticleDOI
Finite element analysis of vehicle-bridge interaction
TL;DR: In this paper, the authors present results of the finite element (FE) analysis of dynamic interaction between a heavy truck and a selected highway bridge on US 90 in Florida using commercial program LS-DYNA and the super computer at the Florida State University.

TL;DR: In this paper, a procedure for characterizing the deformation process of regular cellular structures fabricated with Fused Deposition Modelling of ABSplus material is presented, and two different topologies with similar relative densities were experimentally compressed for five different deformation velocities: quasi static (1.0, 5.0 and 10.0 mm/s) and dynamic (1520.0
Journal ArticleDOI
Deformation of honeycomb cellular structures manufactured with Laser Engineered Net Shaping (LENS) technology under quasi-static loading: Experimental testing and simulation
Paweł Baranowski,Paweł Płatek,Anna Antolak-Dudka,Marcin Sarzyński,Michał Kucewicz,Tomasz Durejko,Jerzy Małachowski,Jacek Janiszewski,Tomasz Czujko +8 more
TL;DR: In this article, two honeycomb topologies with different elementary cells were designed and manufactured from Ti-6Al-4 V alloy powder with the use of Laser Engineered Net Shaping (LENS) system and compressed using a universal strength machine.
Journal ArticleDOI
Fracture and fragmentation of dolomite rock using the JH-2 constitutive model: Parameter determination, experiments and simulations
Paweł Baranowski,Michał Kucewicz,Roman Gieleta,Michał Stankiewicz,Marcin Konarzewski,Paweł Bogusz,Mateusz Pytlik,Jerzy Małachowski +7 more
TL;DR: In this paper, a procedure for determining Johnson-Holmquist II (JH-2) model parameters for dolomite rock was presented, and the parameters responsible for damage and fracture were iteratively obtained based on a proposed drop-weight impact laboratory stand method and numerical simulations.
