Macro- and micro-mechanical perspectives on creep-fatigue interaction in Type 316L stainless steel
No full textCreep-fatigue of Type 316L stainless steel under asymmetric waveforms (specifically slow tension-fast compression, S-F, and fast tension-slow compression, F-S) has been understudied, despite its significant implications as demonstrated in this work. This study bridges macro- and micro-mechanical perspectives through a combined approach, involving high-temperature testing, scanning electron microscopy, X-ray computed tomography, neutron diffraction, and crystal plasticity modelling. Macro-mechanical tests revealed distinct deformation behaviours under S-F and F-S waveforms with and without a 1-hour tensile dwell at 550 °C, with S-F reducing lifespan in both fatigue and creep-fatigue conditions. Post-mortem analyses revealed distinct fracture morphologies induced by tensile dwell, with creep-fatigue S-F specimen exhibiting more pronounced intergranular-dominant fracture and higher internal defect volume. It also exhibited the highest number fraction of medium-sized (10–40 μm) microcracks, which correlates with its shortest fatigue life and more creep damage accumulation. Higher grain-level deformation incompatibility was observed during tensile dwell in the S-F load waveform. Crystal plasticity modelling revealed that the higher tensile stress amplitudes during S-F loading stem from increased dislocation density, with average densities at peak tensile strain during the saturation cycle reaching 186 μm⁻² for S-F and 147 μm⁻² for F-S waveforms. These findings establish a strong link between macroscopic and microscopic behaviours under asymmetric loading, emphasising the potential of S-F waveforms for cost-effective creep-fatigue experiment design. Furthermore, for the asymmetric waveforms studied, creep-fatigue life assessment using the ductility exhaustion method demonstrates greater accuracy than those based on the time fraction method
Treatment of DDH in older children - Aga Khan University Hospital experience
No full textAbstract Introduction: Developmental dysplasia of the hip is a congenital anomaly that is best treated immediately after birth. The deformity, if not treated early, usually progresses with time and becomes more complicated to treat. Its treatment in an older child requires a complete understanding of the primary disease process as well as correction of the secondary anatomical deformities which have matured at that time. In this study, we present our experience with the treatment of this complex problem in older children. Materials & Methods: All patients who presented to us with idiopathic DDH beyond 18 months of age at the Aga Khan University Hospital were included in the study. We operated on 20 patients with 25 hips from 1990 to 1998. There were 13 females and five patients with bilateral disease. The mean age was 48 months and the average follow-up was 13 months. Patients were classified according to the Tonnis class and the acetabular index and the central edge angle were measured both pre- and post-operatively. Functional evaluation was then done using MacKay’s scoring system. Results: There were 7 (28%) hips in the Tonnis class II, 10 (40%) hips in Tonnis class III, and 8 (32%) hips in the Tonnis class IV at the time of presentation. We were able to achieve closed reduction in five (20%) hips, and satisfactory open reduction without any bony procedure was performed in four (16%) hips. The triple procedure of open reduction, femoral and innominate osteotomy was performed in 16 hips in 13 patients. The acetabular index improved from an average of 350 pre-operatively to an average of 180 post-operatively. The MacKay score was good to excellent in 22(88%) hips and we had a failure in 1(4%) hip joint. The Severin class was good to excellent in 21 (82%) patients at the time of final evaluation. There were 3 cases of posterior subluxation and 1 case each of avascular necrosis and myositis ossificans. Conclusions: Tonnis class and age of the patients are important determinants of the final outcome. The triple procedure of open reduction, femoral and innominate osteotomy gives the best results in an older child with DDH
Four kilobyte memory array for Magnetic Random Access Memory development
No full textThesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2007.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (p. 129-131).The circuits for a A 4kb array of Magnetic Tunnel Junctions (MTJs) have been designed and fabricated in a 0:18¹m CMOS process with three levels of metal. Support circuitry for addressing, reading, writing, and test mode probing enables the characterization of the switching of a thin-film ferromagnetic layer in the MTJs. Specifically, novel mechanisms involving spin-transfer or thermal assistance can be studied and compared to current MRAM designs that switch the MTJ with current-induced magnetic fields. Using this array design, both high speed digital and quasi-static dI/dV experiments can be conducted to investigate the nature of the MTJ resistance hysteresis and process variation in addition to the switching behavior under both polarities of current.by Masood Qazi.M.Eng

A Design Tool for Passive Wrist Support
No full textA design tool for passive wrist support using compliant spatial beams as gravity balancer is presented. The aim of this assistive device is to reduce required effort for pronation-supination and flexion-extension by 70% to help patients with muscular weakness keeping their hand’s posture and doing daily tasks, while the forearm is rested. To reach this goal, a setup with three connection points to the user’s hand, and two optimized spatial beams as elastic gravity compensators, are developed. The overall shape and cross-sectional dimensions of the compliant beams are attained using an optimization technique. The objective is reaching a desired endpoint kinetostatic behaviour which is determined based on the hand’s weight and available muscular forces. A design case is presented to show the ability of the method, and the final errors from the desired behaviour are clarified. In the end, possible further applications of the design tool are discussed.Accepted Author ManuscriptMechatronic Systems DesignPrecision and Microsystems Engineerin
