SUMMARY:Santosh Kakarla's PhD thesis defense
DESCRIPTION:Santosh Kakarla will publicly defend her PhD thesis entitled : \n“From anisotropic damage to multiple cracks by coupling a microplane model and a strong discontinuity formulation in the Embedded Finite Element Method”\nFriday 19 June 2020 at 2pm\nVideo conference with the ‘Blackboard Collaborate’ application (see below “Connection Details) \n  \nAbstract\n(.pdf) \nThe performance aspects of large scale civil engineering structures like containment facilities such as durability\, serviceability and structural safety are assessed from time to time to avert any catastrophes. Also\, in the cases of extreme loading\, different cracking mechanisms contribute to each other ultimately leading to the failure. This creates the need for devising certain regulatory measures. In order to achieve this\, it is essential to predict the information like crack opening displacements\, crack spacing and tortuosity. The purpose of this thesis is to develop numerical tools to model multiple intersecting cracks. In particular\, the complete strain localization process from the onset of damage to the initiation and propagation of multiple cracks. Two main ingredients are used. The microplane model allows to describe the anisotropic damage phase and Embedded Finite Element Method (EFEM) introduces cracks as multiple strong discontinuities in the damaged continuum. First\, the standard EFEM is extended in the context of multiple cracks. Later\, the microplane microdamage model is formulated in a thermodynamic framework using simple constitutive laws. Finally\, these two approaches are coupled using a transition methodology. The proposed methodologies are illustrated using several elementary and structural test cases that involve complex stress-strain states. \nJury composition\nPr Jean Baptiste COLLIAT\, Professeur\, Université de Lille – Reporter\nPr Panagiotis KOTRONIS\, Professeur\, EC Nantes – Reporter\nPr Delphine BRANCHERIE\, Professeure\, UTC Compiègne – Reviewer\nDr Ludovic JASON\, Ingénieur chercheur HDR\, CEA – Reviewer\nPr Frédéric RAGUENEAU\, Professeur\, ENS Paris-Saclay – Reviewer\nDr Cédric GIRY\, Maître de conférences\, ENS Paris-Saclay – Thesis Advisor & Reviewer\nDr Giuseppe RASTIELLO\, Ingénieur chercheur\, CEA – Thesis Advisor & Reviewer\nDr Benjamin RICHARD\, Chef de Laboratoire HDR\, IRSN – Thesis Director \nConnection Details\nThe following virtual rooms are dedicated for testing and defense purposes:  \n\nvirtual room for testing: this room is already accessible\n\nhttps://eu.bbcollab.com/guest/64f71474153046d5950fc4d6152802ea \n\nvirtual room for defense: this room is accessible from 1.30pm on the 19/06/2020\,\n\nhttps://eu.bbcollab.com/guest/287dc108002c491d977e3f42f2059398
