Micromechanical understanding of the macroscopic features of dense granular materials
The prevalence of granular materials in nature (soil, beach sand, rubble pile asteroids) and in several industries (cement, food grains, pharmaceutical powders) has motivated extensive research towards understanding the ...
Exploration of Design Thinking in School Education
This thesis comprehensively investigates the integration of design thinking into education, focusing on its application in K-12 settings in India. The broad aims of the research work are:
1. To investigate the need to ...
Investigating and Modelling the Microscopic Pedestrian Behavioral Dynamics in Mass Religious Gatherings
Pedestrian models that can realistically reproduce observed pedestrian movement dynamics are crucial in facility planning and pre-event planning of crowded situations. Despite the elaborate arrangements, crowd disasters ...
Effects of 3d Morphological Characteristics of Sand on Multi-scale Intergranular and Sand-geosynthetic Interactions
To understand the process of mobilization of shear strength in sands and sand-geosynthetic interfaces at a fundamental level, it is essential to precisely characterize the size and shape of the grains and the shear-induced ...
Morphological Perspectives of Sand Liquefaction and its Mitigation
Liquefaction of soils under seismic conditions has profound implications for infrastructure resilience in earthquake-prone regions. Saturated loose cohesionless granular soils have the tendency to readily lose grain contacts ...
Dynamics of Leidenfrost droplets on microtextured substrates
A liquid droplet placed on a heated substrate at temperatures significantly higher than the
saturation temperature of the liquid levitates over a thin film of vapor and is termed as a
Leidenfrost (LF) droplet. Leidenfrost ...
Comparison of Additive and Multiplicative Kinematics in Large Deformation Plasticity
The most widely used plasticity model in commercial finite element analysis software packages
is the additive plasticity model. One of the more well-known alternatives to additive
plasticity is multiplicative plasticity. ...
Simulation of complex plastic flows in metal sliding and cutting
Metal manufacturing encompasses a broad range of mechanical transformation processes that shape native metal into useful forms. These processes generally involve the interaction of a hard tool with a specimen / workpiece, ...
Understanding design communication in internet-enabled remote synchronous collaborative design in the early stages of design
Remote synchronous collaborative design necessitates designers to carry out the design process using web-based real-time communication applications for collaboration with co-designers. Design communication involves exchanging ...
