Modelling spatial and non-spatial conflicts across multiple design domains
This thesis aims to detect spatial and non-spatial conflicts in product design arising out of requirements in different design domains. Handling such conflicts requires modelling the non-geometric knowledge outside the ...
Posturing for Autonomous Digital Human Model
Digital Human Models (DHMs) are representations of humans in virtual environments that have applications in diverse disciplines. In the context of engineering design, DHMs are used to assess if a proposed design satisfies ...
Design and Development of Hybrid Metal and Polymer Additive Manufacturing System
Additive manufacturing (AM) is a layer-based manufacturing process aimed at producing parts directly from a Computer-aided design (CAD) model. There are various types of AM systems, which can be classified based on: (i) ...
Standoff Target Tracking Guidance using Line-of-Sight Distance Bifurcation
Unmanned aerial vehicle (UAV) applications that continue to receive significant attention are target acquisition and tracking. There exist many paths to track a stationary target from a prescribed altitude. The most widely ...
Classical Approach to Understanding the Impact Dynamics of Hollow Droplets
Compound droplets are utilized in applications ranging from the preparation of emulsion to
biological cell printing and additive manufacturing. Here, we report on the impact dynamics of
a compound hollow droplet on a ...
Experimental and numerical studies on Mode-I ductile fracture behaviour of Magnesium
In recent years, weight reduction of automobiles is being achieved by using light weight metals like magnesium (Mg) in the form of cast or wrought products. However, the structural application of Mg and its alloys is limited ...
Estimation and Control of Friction in Bulk Plastic Deformation Process
Friction plays a significant role in bulk plastic deformation processes in controlling the tool life, formability of the work piece material and the quality of the finished product such as, surface finish, microstructure ...
Blade Flutter in a Linear Cascade: Unsteady Loads and Flow Features in Subsonic and Transonic Flows
Vibration related issues like flutter can significantly limit the performance of aircraft engines and cause unwarranted cost and time overruns. The increased demand for more powerful yet compact engines has resulted in the ...
Processing, Structure and Properties of Friction Stir Process Derived In-situ Nano Composites and Foams
High specific-strength materials with high toughness can reduce the weight of automobile and aerospace components. Lightweight components for these applications are essential, as they can significantly improve fuel efficiency. ...
