Abstract

Wire rope is a critical component in industrial crane systems, susceptible to structural failure due to cyclic loading, fretting wear, and corrosion. Prior reviews have addressed failure mechanisms or Non-Destructive Testing (NDT) methods in isolation, without integrating both perspectives or incorporating Indonesian national literature. This study systematically analyzes wire rope structural failure mechanisms and comparatively evaluates the effectiveness of various NDT methods through a Systematic Literature Review (SLR) following the PRISMA protocol. Searches across Scopus, ScienceDirect, Google Scholar, and Portal Garuda (2002–2025) identified 159 articles, of which 35 met the inclusion criteria. Literature quality was assessed using an adapted CASP/NOS rubric, yielding a mean score of 7.2/10. Findings indicate that fatigue induced by fretting wear is the most frequently reported failure mode (84% of studies), with Von Mises stress concentrations at strand-sheave contact points consistently exceeding the yield strength of wire steel (≈650 MPa). Among NDT methods evaluated, Magnetic Flux Leakage (MFL) demonstrated the highest relative performance, with defect classification accuracy reaching 95.3% and a minimum detectable metallic area loss of 1–2% under laboratory conditions. Synthesis of findings yields a conceptual framework for NDT- and condition-based maintenance (CBM)-integrated wire rope integrity management as the principal contribution of this study.

Abstract

Recycled high-density polyethylene (rHDPE) offers a sustainable alternative to virgin plastics, but repeated processing can degrade its mechanical properties, motivating reinforcement with natural fibers and fillers. This study investigated the combined effect of coir fiber and rice husk ash (RHA) on the mechanical and burning-rate characteristics of rHDPE composites using a two-stage experimental design. In Stage 1, coir fiber content (5, 10, and 15 vol.%) was varied to determine the optimum reinforcement level based on impact strength. In Stage 2, the selected optimum fiber content was combined with RHA (5 and 10 vol.%) to evaluate tensile strength and burning behavior, tested according to ASTM D638, ISO 179, and ASTM D635, respectively. Results showed that 10 vol.% coir fiber produced the highest impact strength (16.36 kJ/m²), while higher fiber loading reduced toughness due to agglomeration and void formation. The composite with 5 vol.% RHA exhibited superior tensile strength (10.46 ± 1.23 MPa), whereas 10 vol.% RHA improved ignition resistance, extending ignition time to 14 s. These findings demonstrate that alkali-treated coir fiber and RHA can enhance rHDPE performance, supporting the valorization of plastic and agricultural waste into sustainable composite materials.

Abstract

Dental implants in the posterior maxilla often require angulated abutments due to anatomical limitations. However, increased abutment angulation may influence stress distribution and compromise mechanical integrity. This study aimed to evaluate the biomechanical behavior of implant components with 15°, 17°, and 20° abutment angulations using three-dimensional finite element analysis (FEA). A static vertical load of 276 N was applied to a D4-type bone block model. Results showed that higher abutment angles led to increased von Mises stress and strain, particularly on the abutment U-profile and the screw head. Despite the rising stress, all configurations maintained safety factors above 1.5. These findings indicate that angled abutments up to 20° are mechanically safe under axial loading conditions, supporting their use in clinically challenging posterior maxillary regions.
