Indentor tests are one of the most common ways for in vivo estimation of human residual limb soft tissue bulk elastic and viscoelastic material properties. Due to large strains and displacements encountered during indentation, elementary strength of materials approaches yield crude approximations of the material properties. A common procedure, therefore, is to construct a finite element model of the tissue in the vicinity of the test site. The material properties of soft tissue are identified by matching the force-displacement characteristics of the finite element model to that of indentor experiments. The effect of residual limb surface curvature on force-displacement characteristics of finite element models are investigated. Results indicate that limb surface curvature effects are negligible compared to other modeling assumptions.

Effect of hardening models on different ductile fracture criteria in sheet metal forming
Dizaji, Shahram Abbasnejad; Darendeliler, Haluk; KAFTANOĞLU, BİLGİN (2016-07-01)
Prediction of the fracture is one of the challenging issues which gains attention in sheet metal forming as numerical analyses are being extensively used to simulate the process. To have better results in predicting the sheet metal fracture, appropriate ductile fracture criterion (DFC), yield criterion and hardening rule should be chosen. In this study, the effects of different hardening models namely isotropic, kinematic and combined hardening rules on the various uncoupled ductile fracture criteria are in...
Effects of Isoflurane, Halothane, and Chloroform on the Interactions and Lateral Organization of Lipids in the Liquid-Ordered Phase
Türkyılmaz, Serhan; Regen, Steven L. (2011-12-06)
The first quantitative insight has been obtained into the effects that volatile anesthetics have on the interactions and lateral organization of lipids in model membranes that mimic "lipid rafts". Specifically, nearest-neighbor recogntion measurements, in combination with Monte Carlo simulations, have been used to investigate the action of isoflurane, halothane, and chloroform on the compactness and lateral organization of cholesterol-rich bilayers of 1,2-dipalmitoylsn-glycero-3-phosphocholine (DPPC) in the...
Effects of biomimetic synthesis route and sintering temperature on physicochemical, microstructural, and mechanical properties of hydroxyapatite
Kaya, Yasemin; Jodati, Hossein; Evis, Zafer (2021-01-01)
Biomimetic synthesis of bioceramics using simulated body fluid (SBF) is a route to produce biomaterials with a more suitable microstructure and characteristics required for bone defect treatments. As matter of fact, the biomimetic method allows us to imitate the natural environment needed for the synthesis of bone-like materials, such as hydroxyapatite (HA). In this study, biomimetic HA was successfully synthesized through the microwave-assisted method by the employment of SBF in different ratios with water...
Design and verification of diamond based capacitive micromachined ultrasonic transducer
Çetin, Ahmet Murat; Bayram, Barış; Department of Electrical and Electronics Engineering (2011)
Potential applications such as high intensity focused ultrasound in medical therapeutics require larger output pressures. To offer unprecedented acoustic output pressure in transmit without the limitations, Capacitive Micromachined Ultrasonic Transducer operation modes of collapse and collapse-snapback are introduced in literature. Both operation modes require the membrane to contact the substrate surface, which poses a problem on the durability of the membrane in terms of structural integrity and tribologi...
Effect of chemical structure on properties of polyurethanes: Temperature responsiveness and biocompatibility
Komez, Aylin; Buyuksungur, Senem; Hasırcı, Vasıf Nejat; Hasırcı, Nesrin (2018-09-01)
Polyurethanes are known as one of the most biocompatible and inherently blood-compatible materials and have a wide range of applications in the medical field due to their controllable structure and properties. Durability, elasticity, elastomeric structure, fatigue resistance, versatility, and easy acceptance by the biological media after the application makes these polymers preferable in medical area. In this study, polyurethane films were prepared using poly(propylene-ethylene glycol) and either toluene-2,...
