Dr. Sarra Haouala obtained her Mechanical Engineering degree from Ecole Nationale d’Ingénieurs de Tunis (Tunisia) in 2010 and her Master degree in Mechanics from the same institution in July 2011. The topic of the master thesis is: “Modeling and numerical simulation of the flow of dry/wet cohesive granular materials using the discrete element method (DEM)”.
From September 2011 to January 2012 she worked as an Assistant at the Private School of Engineering and Technology in Tunisia.
In February 2012 she joined the department of Applied Mechanics and Mathematics (MEMA) at Université catholique de Louvain (UCL), Belgium, where she started her PhD. entitled Space and time (4D) homogenization of coupled viscoelastic-viscoplastic solids under large numbers of cycle. (Funded by Walloon Region through the EUREKA/DURAFIP project).
Obtaining her PhD in January 2016, she moved to Madrid to work as a Postdoctoral Researcher in IMDEA materials institute.

Current Research Projects:

Past Research Projects:
January 2015-September 2015
MECATECH CLUSTER-Funding: Walloon Region
Objective: The aim was to increase the recyclability of steel mill slag by recovering the fractions for which there are no or few outlets and using them to make materials for the building and public works (BPW) sector.
Role: I worked on modeling the behavior of the material under different loading cases: Creep, relaxation tensile tests under different strain rates, using mean-field homogenization and finite element calculations.
2- Long Fiber-reinforced Thermoplastics (LFT)
January 2013- December 2013
Walloon Region project with international partners
Objective: Material and structural modeling of long fiber reinforced injected thermoplastics.
Role: I worked on the effect of spatial distribution on the effective behavior of composite materials. Classical mean-field homogenization (MFH) supposes that fibers or particles are randomly dispersed in a Representative Volume Element (RVE). It does not take into account clustering for instance. The objective of this work was to enrich MFH in order to include certain types of spatial distributions. Two theories: Ponte-Castaneda and Willis (1995); El Mouden and Molinari (1995).
February 2012- September 2015
EUREKA/Walloon Region project
Objective: Material modeling of durability of fiber reinforced polyamide.
Role: I worked on the development of numerical homogenization methods to improve accuracy and speed up fatigue FEA.
