Pin-on-plate and pin-on-disk wear tests are typically used for assessing the behavior of a given material coupling estimating its coefficient using Archard law. This study investigates differences in law pin-on-plate cases, particularly flat-ended pins. Both analytical finite element models two were developed, assuming 21 N normal load 50π mm sliding distance. In simulations three different distances between pin disk axes considered, i.e., 1.25–2.5–5 times radius (5 mm). For results,...
The paper introduces a tool called Automatic Scaling Tool (AST) designed for improving and expediting musculoskeletal (MSK) simulations based on generic models in OpenSim. is crucial initial step MSK analyses, involving the correction of virtual marker locations model to align with actual experimental markers. AST automates this process by iteratively adjusting markers using scaling inverse kinematics static trial. It evaluates root mean square error (RMSE) maximum error, implementing...
Preclinical wear evaluation is extremely important in hip replacements, being one of the main causes failure. Experimental tests are attractive but highly cost demanding; thus predictive models have been proposed literature, mainly based on finite element simulations. In such simulations, effect friction usually disregarded, as it considered not to affect contact pressure distribution. However, a frictional could also result shift location nominal area, which can modify maps. The aim this...
Summary Finite element simulation is a powerful tool to study and predict the wear behavior of different mechanical systems. However, high computational cost required obtain accurate numerical solutions crucial aspect especially for large complex models. The present proposes possible solution overcome this limitation by exploiting potentiality submodeling technique, whose application problem still rare in literature. A global‐local approach analysis presented validated simple pin‐on‐disk...
Total knee replacement (TKR) is one of the most performed orthopedic surgeries to treat joint diseases in elderly population. Although survivorship implants may extend beyond two decades, poor outcome rate remains considerable. A recent computational approach used better understand failure modes and improve TKR outcomes based on combination musculoskeletal (MSK) finite element models. This combined multiscale modeling a promising strategy field biomechanics; however, some critical aspects...
Perivascular epithelioid cell tumors (PEComas) are rare mesenchymal tumors. One of the most frequent localizations PEComas is female genitourinary tract, and uterus involved site after kidney. Correct preoperative diagnosis rarely achieved due to presence nonspecific imaging features. We report a case uterine PEComa with particular reference ultrasound's role in characterizing this occurrence.a 45-year-old White woman came our observation for cyclic abdominopelvic pain chronic constipation....
Introduction: The use of cyanoacrylate glue as sealant on the exit site peripherally inserted central catheters (PICCs) may offer some important clinical advantages. However, concerns exist about potential interaction between and material catheter itself. aim this study was to investigate possibility damage secondary a long-term contact with two-component skin (N-butyl + octyl cyanoacrylate). Methods: Twelve PICCs different brands types were selected (11 made polyurethane one silicon). glued...
Non-invasive methods for assessing fracture healing are crucial biomedical engineers. An approach based on mechanical vibrations was tried out in the 1990s, but soon abandoned due to insufficiently advanced technologies. The same is re-proposed present study order monitor process of a lengthened femur with an external fixator. pins screwed into bone were exploited impact testing (IT) excite and capture its response. Transmission through soft tissues thus prevented, quality signals improved....
The correct evaluation of the healing process is important to define proper times fixator dynamization and removal, avoiding refractures. Unfortunately, a quantitative assessment not yet available in clinical practice. aim paper prove feasibility mechanical vibration method assess bone fractures treated with external fixation, vivo conditions. case study was patient tibial fracture monoaxial fixator. monitored for three months through series five impact tests. pins screwed into were used...
