- The paper compares three methods for testing floor slip resistance using various types of granite slabs.
- It analyzes the acceptance angle values, slip resistance values, and sliding friction coefficients to evaluate the correlation and precision of each testing method.
- The study concludes that the choice of testing method significantly impacts the assessment of slip resistance, especially for low roughness slabs, which can lead to safety risks in building use.
Article Abstract
This paper attempts to compare three methods of testing floor slip resistance and the resulting classifications. Polished, flamed, brushed, and grained granite slabs were tested. The acceptance angle values (α) obtained through the shod ramp test, slip resistance value (SRV), and sliding friction coefficient (μ) were compared in terms of the correlation between the series, the precision of each method, and the classification results assigned to each of the three obtained indices. It was found that the evaluation of a product for slip resistance was strongly related to the test method used and the resulting classification method. This influence was particularly pronounced for low roughness slabs. This would result in risks associated with inadequate assessments, which could affect the safe use of buildings facilities.

Understanding the dynamic response of granular shear zones under cyclic loading is fundamental to elucidating the mechanisms triggering earthquake-induced landslides, with implications for broader fields such as seismology and granular physics. Existing prediction methods struggle to accurately predict many experimental and in situ landslide observations due to inadequate consideration of the underlying physical mechanisms. The mechanisms that influence landslide dynamic triggering, a transition from static (or extremely slow creeping) to rapid runout, remain elusive.

Transport equipment manufacturers in the automotive and aerospace industries are focused on developing materials that enhance fuel efficiency and reduce carbon dioxide emissions. A significant approach is employing lightweight materials like aluminum, magnesium, and polymer-based composites. Polyamide-based composites, particularly nylon 66, as viable alternatives due to their excellent rigidity, chemical resistance, and thermal stability are investigated to address the limitations of traditional thermosetting resins, which are difficult to recycle and have lengthy molding processes that hinder mass production.

Due to limited slip systems activated at room temperature, the plastic deformation of Mg and its alloys without any preheating of initial billets is significantly limited. To overcome those issues, new methods of severe plastic deformation are discovered and developed. One such example is extrusion with an oscillating die, called KoBo.

This study explores the fatigue behavior and fracture mechanisms of TC11 titanium alloy formed by laser metal deposition (LMD) and subjected to double annealing. The research focuses on how the alloy's unique microstructure, consisting of alternating equiaxed and columnar crystals, influences its fatigue performance. The microstructure's basket-like α' phase, made up of both plate-shaped and needle-like structures, leads to variations in crack growth behavior, as shown in the relationship between the crack growth rate and the stress intensity.

Titanium (Ti) and its alloys are used in various applications, including aircraft frames, ship parts, heat exchangers, and evaporator tubes, because of their extraordinary properties, such as high specific strength, excellent corrosion resistance at high temperatures, good castability, and weldability. Plastic deformation plays a crucial role in securing the appropriate microstructure and strength of Ti and alloys in these applications. The rolling process, one of the most useful methods for plastic deformation, causes efficient deformation inside the materials, resulting in grain refinement, dislocation slip, and twinning.
