Background:

Elisa completed her Masters degree in Physics at the University of Lecce (Italy) in 2003. She obtained the PhD in Innovative Materials and Technologies in 2007 at the Superior Institute of Interdisciplinary Education of the University of Salento (Italy) under the supervision of Prof R. Cingolani, working on nanofabrication strategies for organic optoelectronic devices.

In 2005, Elisa won a Marie Curie fellowship at the Foundation for Research and Technology Hellas (FORTH), Heraklion (Greece) for developing surfaces with optically switchable wettability. In 2008, she became a Post-doc Research Associate in the group of Prof. D. A. Weitz at the Department of Physics of Harvard University, where she acquired expertise on microfluidic devices for the production of hydrogel micro-particles and for investigating the biophysical properties of normal and diseased renal glomeruli.

During the appointments as Post-doc Research Associate at the National Nanotechnology Laboratory and at the Centre for Biomolecular Nanotechnologies (Lecce, Italy), Elisa worked on microfluidic platforms integrating functional elements for DNA amplification, food safety and for studying the growth and differentiation of human renal stem cells.

From 2012 to 2015, Elisa was Research Group Leader at the Nanophysics Department of the Italian Institute of Technology (IIT), Genoa (Italy), conducting research on biopolymers derived from natural sources, such as plants and marine environment, with application in tissue engineering for skin regeneration and in drug delivery systems. In April 2015, she joined the Department of Materials of Loughborough University as Senior Lecturer in Polymer Science.

Selected publications:

This is some our most recent work to understand the spallation mechanics of thin films. It draws on the understanding developed in our theoretical work on the interfacial fracture of layered materials. Excellent agreement with independently-obtained experimental measurements is obtained.

Fracture between dissimilar interfaces is an important consideration in the design and application of composite materials and structures, for example, to determine the toughness against fracture or spallation. It has, however, proved an extremely challenging problem for decades to obtain analytical solutions for the complex stress intensity factors and the crack extension size-dependent energy release rates based on 2D elasticity. These papers achieve a solution and present elegant analytical formulae.

These two papers present Loughborough’s mixed-mode fracture partition theories in an easy-to-use format. They are helpful references for researchers carrying out mixed-mode fracture toughness testing. They also make comparisons between the theories and several sets of independently-obtained fracture toughness test data. A key observation is that Loughborough’s Euler/classical beam-based partition theory gives the best predictions for the mixed-mode fracture toughness of the graphite/epoxy fibre-reinforced composite laminates.

This early paper presents the fundamentals of Loughborough’s powerful orthogonal pure fracture mode methodology, and analytical formulae for mixed-mode partition theories based on Euler/classical beams and Timoshenko/first-order shear-deformable beams, and an approximate rule for 2D elasticity-based partitions. It underpins all the subsequent developments. It is a helpful paper for those wishing to understand in detail the fundamental mechanics of mixed-mode fracture.
