I am Indrajeet Patil from India. My enthusiasm towards the silhouette of tall superstructures in today’s rapid urbanization and the subtle art by which these “mighty giants” are designed to obey the laws of Strength, Stiffness, Stability and Synergy inspired me to pursue a Bachelor of Civil Engineering from SPPU (University of Pune), India. I further moved to the United Kingdom to pursue a Master of Science (M.Sc.) in Structural Engineering from the University of Glasgow, Scotland. An outstanding academic record coupled with a rich industrial practice as a consulting engineer are the fundamental roots of my engineering excellency.

Along with studying engineering structures, I further developed a multi-disciplinary approach into biomechanical, aerospace, and mechanical engineering. My master’s degree thesis comprised of developing a sophisticated numerical model and nonlinear simulation of adaptive bone remodelling process in proximal femur based on an open system thermodynamics approach (time-dependent density, local creation of mass etc.) with an interesting extension of the femur bone as a biomimetic inspiration in structural engineering. Several other sci-fi inspired research projects in my course, such as space elevator dynamics and mathematical modelling of tethered space systems although far away from reality, were an enjoyable way to learn highly complex theories in nonlinear dynamics and computational science. Structural forensics and fracture mechanics have also been a key part in my research and industrial practice.

My research interests in multibody dynamics, geometrically exact formulations, contact mechanics, large-deformation structures, vibration and crowd dynamics and multiscale modelling along with a passionate drive to obtain a doctorate inspired me to take part in the THREAD project. As a fellow ESR, understanding the nonlinear behaviour of highly flexible slender structures, their interactions, and mathematical constraints to provide groundbreaking advancements in the industry is a challenging opportunity for which I am fully equipped and confident to excel in. This project shall help me to develop a strong network of brilliant fellow scientists, collaborate with industrial partners, and explore new settings in the academia to break new grounds in research, and finally unlock several doors to a bright career in research.

Host Institution
University of Liège (Belgium)


Development and analysis of local frame methods for the simulation of textile manufacturing processes: modelling of continuous 1D yarn and cable structures with geometric nonlinearities, representation of contact conditions based on the non-smooth contact dynamics approach, numerical discretisation methods in space and time using Lie group interpolation and efficient solution algorithms for non-smooth flexible multibody systems on Lie groups.

Expected Results

ESR2 will establish a finite element formulation for cables and rods with contact based on the local frame approach. Besides theoretical investigations, the method will be implemented in the finite element simulation code Oofelie jointly developed by ULG and GDTECH and will be applied to model the textile braiding process. The simulation should allow to predict the influence of some key parameters of the braiding machine on the final product layout. ESR2 will also benefit from close interactions with ESR3 for the development of the modelling and simulation tool.
