  Publikacja

  • A. Sabik

  - COMPOSITES PART B-ENGINEERING - Rok 2018

  The majority of fiber reinforced composites exhibit strong non-linear behavior in in-plane shear state. The effect is attributed to the micro-cracks appearing in the matrix and can be modeled on the micro and macro level. In this work the author proposes constitutive laws describing the non-linear in-plane shear response, which can be alternative for the relations commonly considered in the literature. The proposed equations are...

  Polymer recycling techniques experience a maturity period of design and application. Rubbers comprise a high proportion of polymer wastes, highly flammable and impossible to re-melt. Polymer composites based on ground tire rubber (GTR) and ethylene-vinyl acetate copolymer (EVA) containing carbon black (CB) (1–50 phr), with variable EVA/GTR weight composition (10/90, 25/75, 50/50, 75/25 and 90/10), and processing temperature (Low:...

  - Materials - Rok 2021

  Due to growing restrictions on the use of halogenated flame retardant compounds, there is great research interest in the development of fillers that do not emit toxic compounds during thermal decomposition. Polymeric composite materials with reduced flammability are increasingly in demand. Here, we demonstrate that unmodified graphene and carbon nanotubes as well as basalt fibers or flakes can act as effective flame retardants...

• Algorytmy numeryczne obliczania pseudokątów wiążących typu B

  Publikacja

  • T. Wronowski

  - Rok 2005

  Referat tematycznie związany jest z teoretycznymi podstawami funkcjonowania technologii pomiarowej bazującej na stanowiskach swobodnie zorientowanych. Przedstawiono algorytmy obliczania pseudoobserwacji kątowych typu B (zwanych pseudokątami), wiążącymi sieć punktów odniesienia ze stanowiskami pomiarowymi. Pseudokąty wiążące typu B wykorzystuje się w sieciach obliczeniowych typu B.
