  - ENGINEERING FAILURE ANALYSIS - Rok 2014

  Presence of geometric notches in welded joints causes concentration of strains and stresses, therefore reducing fatigue strength of such joints. This article presents an analysis of stress concentrations in a fillet weld of a spreader mounting bracket on a small sailing yacht. The aim of this article is to direct the attention of designers, manufacturers and regulatory bodies to issues of fatigue cracks that form in brackets fastening...

  Welding is the basic method of joining ship hull elements during its construction. However, this method of joining structural elements generates shrinks. Shrinks causes deformation of the entire welded structure, both linear and angular. In the shipbuilding industry, there is a tendency to oversize fillet welds, at the design as well as manufacturing...

  Typical (normative) testing of materials and/or welded joints do not answer on all questions about material or welded joint properties. In ship building and off-shore sectors, many strucures requires materials and joint with higher than typical fatigue resistance. Imact tests, which are carried out during welding technology qualification, gives answer about ductility, CTOD tests results about material or welded joint ability...

  Kontrola jakości wody w basenach kąpielowych może być prowadzona poprzez oczyszczanie wody z uwzględnieniem filtracji i dodawaniemśrodków dezynfekcyjnych. Zanieczyszczenia wody nie zawsze mogą byćskutecznie usuwane przy stosowaniu konwencjonalnych metod uzdatnianiawody. W doświadczeniu zbadano osady powstałe na złożu piaskowym,stwierdzono nieefektywną pracę filtrów piaskowych. Porównano dwazłoża filtracyjne: piasek kwarcowy i...

  - POLYMER TESTING - Rok 2022

  The research work carried out so far indicates the ever wider possibilities and demand for shaping composite products in the rotational molding technology. This trend was the main reason to use waste-based filler from the metallurgical process as a filler for manufacturing polylactide (PLA)-based remolded composites. Copper slag (CS) was introduced in the single-step processing method to PLA matrix at 5, 10, 20, and 35 wt%. The...

  - Polish Maritime Research - Rok 2022

  The welding process is the basic technique of joining in the shipbuilding industry. This method generates welding distortions that cause a lot of problems during the manufacturing process due to both the time and cost of straightening as well as their influence on later stages of production. Proper preparation of welding processes plays a growing role in the shipbuilding industry and the development of calculating tools is being...

  - Polymers - Rok 2022

  The development of new polymer compositions characterized by a reduced environmental impact while lowering the price for applications in large-scale production requires the search for solutions based on the reduction in the polymer content in composites’ structure, as well as the use of fillers from sustainable sources. The study aimed to comprehensively evaluate introducing low-cost inorganic fillers, such as copper slag (CS),...
