Phd position dynamic damage / Marie Skłodowska-Curie – HORIZON 2020

Phd subject :The goal is to work on dynamic damage for ductile materials. Several key points need to be discussed in the phd : (1) in experiments, voids have shapes which are not spherical or spheroidals. We aim to propose a solution to relax the constraint of spheroidal voids by considering cylindrical voids which can be viewed as penny shape inclusions. A model will be developed and comparisons with finite element calculations will be carried out. (2) Based on 2D simulations, various loading conditions will be investigated. We will investigate the case of shear loading in which the void-shape changes upon deformation and the semi axes of the void are rotating. An important challenge consists in modeling both aspects under low triaxiality loading and high strain rates. (3) in case of spherical voids under axisymmetric loading but with various Lode parameters, it is of interest to understand how local acceleration in the matrix influences the macroscopic stress. This aspect is fundamental. Based on precise description of the acceleration field in the matrix, we will explain how the void surface is strongly influenced by the dynamic loading. For that purposes, dedicated representative volume element containing initially a spherical void under axisymmetric loading are simulated under constant homogeneous stress rate loading.The ESR will work at the UL (in the LEM3 laboratory, Metz, France) with Professors C. Czarnota, S. Mercier and A. Molinari.We are looking for highly motivated candidates who want to pursue a scientific career in mechanical engineering (academic or industrial). An ideal candidate would have a background in mechanical or civil engineering or physics or mathematics and a strong interest in collaborating with a team working attitude in an interdisciplinary project. Good communication in English is required.To apply for the proposed thesis in France, and in order to meet the specific requirements of the Marie Skłodowska-Curie funded PhDs, you must not have resided or carried out your main activity (work, studies, etc.) in France for more than 12 months in the last 3 years. Candidatesmust have a MSc degree or obtain a MSc degree by August 2016.The details of the position is provided in the pdf file.

Phd position on delamination and interface strength in printed circuit board : H2020 Marie Skłodowska-Curie program

Phd subject :A printed circuit board is a passive component which allows to interconnect electronic components soldered on the outer layers in order to realize a complex electronic system. It is a complex multi-layer assembly developed for a very specific goal which requires expertise in mechanical and material sciences. In order to reach the expected performance and lifetime in harsh environments dedicated high-performance base materials are required. During its lifetime, the PCB undergoes a large number of thermal cycles which can lead to the breakup of copper path. In addition, when active components are soldered on the PCB, a thermal shock is produced. It has been detected that the use of certain combination of based materials leads to delamination, which damages the PCB and limits its service-life. We will investigate the delamination process and the evolution of the strength of interfaces from both theoretical and experimental sides. Within this context, we will develop a research on the damage and failure processes of PCBs subjected to thermal cycling. A theoretical model will be specifically developed in order to predict the onset and evolution of damage and failure. The predictions of the theoretical model will be compared with own experiments specifically conducted for that purpose (to check the reliability of the model predictions). The planned experiments are peeling tests at various temperatures performed for various pairs of materials frequently used to manufacture the PCBs.The candidate will work at the LEM3 laboratory, in Metz, Université de Lorraine. The phd subject is in strong collaboration with CIMULEC, a SME manufacturing printed circuit boards for aerospace applications.
We are looking for highly motivated candidates who want to pursue a scientific career in mechanical engineering (academic or industrial). An ideal candidate would have a background in mechanical or civil engineering or physics or mathematics and a strong interest in collaborating with a team working attitude in an interdisciplinary project.The candidate must have some interests to develop both experimental, numerical and modeling researches. Good communication in English is required.
