  - Rok 2012

  Przedstawiono wyniki badań właściwości wytrzymałościowych, modułów stratności i zachowawczych oraz temperatur zeszklenia bioelastomerów zawierających skrobię ziemniaczną lub kukurydzianą. Zbadano także wpływ skrobi oraz czasu wulkanizacji na wybrane właściwości wytworzonych materiałów kompozytowych.

• Dynamics of Chains as a Tool to Study Thermomechanical Properties of Proteins.

  Publikacja

  • P. Weber

  - Rok 2021

  Polymer dynamics can be formulated on different levels of detail. One approach eliminates microscopic degrees of freedom and a polymer molecule is represented by a simplified structure—a chain. In the simplest case monomers of ideal chain have fixed length, and their orientation is independent of the orientations and positions of neighbouring monomers. This is reason that two monomers can co-exist at the same place. Ideal chain...

• Geometry of cycling track

  Publikacja

  • M. T. Solarczyk

  - Budownictwo i Architektura - Rok 2020

  The paper describes the problems related to shaping of the geometry of the cycling track. The method of selection of the angle at the track curve is presented. Issues related to the selection of the appropriate transition curve and the superelevation section along the transition curve are presented. Reference to the recommendations presented in the literature and scientific papers has been made. Special attention...

• Singular curves in the resultant thermomechanics of shells

  Publikacja

  • W. Pietraszkiewicz
  • V. Konopińska-Zmysłowska

  - INTERNATIONAL JOURNAL OF ENGINEERING SCIENCE - Rok 2014

  Some geometric and kinematic relations associated with the curve moving on the shell base surface are discussed. The extended surface transport relation and the extended surface divergence theorems are proposed for the piecewise smooth tensor fields acting on the regular and piecewise regular surfaces. The recently formulated resultant, two-dimensionally exact, thermodynamic shell relations - the balances of mass, linear and angular...

  Friction stir welding (FSW) of polymeric materials has recently attracted significant attention. Herein, we present the effect of the tool pin profile on the FSW of high-density polyethylene (HDPE) joints through joint experimental analysis and thermomechanical simulations. For analysis of pin profile effects on the thermomechanical properties of HDPE joints, frustum (FPT), cubic (CPT), and triangular (TPT) pin shapes were selected...

  • Ł. Zedler
  • K. Formela

  - Rok 2021

  Polyurethane foams are very versatile materials applied in different branches of industry. Their popularity is attributed, among others, to the flexibility in engineering their mechanical performance by the adjustment of their formulations. One of the most crucial factors is the isocyanate index, determining the ratio between the free hydroxyl and isocyanate groups present in the polyurethane system. By the change of this ratio,...

  The copolymerization of styrene (St) with a bioderived monomer, pentadecylphenylmethacrylate (PDPMA), via atom transfer radical polymerization (ATRP) was studied in this work.The copolymerization reactivity ratio was calculated using the composition data obtained from1HNMR spectroscopy, applying Kelen-Tudos and Finemann-Ross methods. The reactivity ratio of styrene (r1=0.93) and PDPMA (r2=0.05) suggested random copolymerization...
