Studies On Momentum, Heat And Mass Transfer In Binary Alloy Solidification Processes
(Indian Institute of Science, 2007-06-06)
The primary focus of the present work is the development of macro-models for numerical simulation of binary alloy solidification processes, consistent with microscopic phase-change considerations, with a particular emphasis ...
Discrete particulate description of elastic structures undergoing geometrically nonlinear deformation and dynamic particle interaction
The mechanical behaviour of deformable bodies in a particulate environment has been an area of increasing interest across a wide spectrum of systems and scale. A composite ensemble of deformable structures and discrete ...
Multi-linear Disassembly Path Determination: A Geometric Approach
This thesis presents a geometric approach for determining the orientation-preserving disassembly paths of polyhedral
assembly components. Exact disassembly path determination of the components is essential because the ...
Topological Derivative-based Optimization of Fiber-reinforced Structures, Coupled Thermoelastic Structures, and Compliant Mechanisms
The topological derivative of a functional quantifies the sensitivity with respect to an infinitesimal domain perturbations such as a hole, an inclusion, a source term, a crack, etc. In this thesis, topological derivatives ...
Microstructure, mechanical behavior, and thermal stability of in-situ polymer-derived ceramic reinforced Al-based composites
Al-based metal matrix composites (MMCs) show a high strength-to-weight ratio which makes them attractive for the aerospace and automobile industries. The reinforcements for the same have conventionally been micron-sized ...
A shape optimization approach for simulating contact of elastic membranes with rigid obstacles
The obstacle problem consists in computing equilibrium shapes of elastic membranes in contact with
rigid obstacles. In addition to the displacement u of the membrane, the interface on the membrane
demarcating the ...
Development of a Flexible Actuator and Motion Planning for Endoscopic Robots
Endoscopy is a procedure by which a long
flexible device called the `endoscope' is inserted
into a patient's gastro-intestinal(GI) tract primarily for diagnosis. An endoscope is typically
equipped with a camera, ...
New Mechanical Methods to Join Sheets in Lap and Butt Configuration and Analytical Model to Predict and Improve Clinching Joint Strength
Mechanical joining of sheets has many advantages over other joining methods in terms of wide variety combination of similar, dissimilar and non-metallic material sheet joining.
In conventional SPR joining, the rivet and ...
