In recent years, Machine Learning (ML) has become increasingly prominent in Solid Mechanics. Its diverse applications include extracting unknown material parameters, developing surrogate models for constitutive modeling, advancing multiscale modeling, and designing architected materials. In this Journal Club, we will focus our discussion on the recent advances and challenges of ML when experimental data is involved. With broad community interest, as reflected by the increasing number of publications in this field, we have recently published a review article in Applied Mechanics Reviews titled “Recent Advances and Applications of Machine Learning in Experimental Solid Mechanics: A Review”. Moreover, a recent insightful paper from Prof. Sam Daly’s group also discussed some perspectives in this field. In this Journal Club, we would like to introduce and share insights into this exciting field.

We have a fully-funded position for a PhD student in the EMSI lab, in mechanical engineering at EPFL, and are seeking qualified applicants. The thesis topic is: Crack front stability in 3D. Information about our lab can be found on our website at: Engineering Mechanics of Soft Interfaces ‐ EPFL

What we seek: 

Dear motivated PhDs of India, 

There is an opprtunity to work on experimental and numerical fracture mechanics using the prestigious National Post Doctoral Fellowship (N-PDF) by SERB India.

The details are available at: https://serbonline.in/SERB/npdf

We can have a discussion for a topic in Fracture Mechanics experimental and/or numerical. The scheme is opening on 3rd July 2023. 

Eligible candidates may contact me at : abhishek.tiwari@iitrpr.ac.in

A research fellow position is available at University of Pavia in Italy starting February-May 2023. The position is part of a project in collaboration with Technion - Israel Institute of Technology. Interested candidates are encouraged to contact Prof. Giulia Scalet (giulia.scalet@unipv.it).

Abstract: A simple nonlocal field theory of peridynamic type is applied to model brittle fracture. The kinetic relation for the crack tip velocity given by Linear Elastic Fracture Mechanics (LEFM) is recovered directly from the nonlocal dynamics, this is seen both theoretically and in simulations. An explicit formula for the change of internal energy inside a neighborhood enclosing the crack tip is found for the nonlocal model and applied to LEFM.

I am seeking a full-time Postdoctoral Research Fellow in Phase-Field modelling of fracture to join the Design of Machines group at the Polytechnic Engineering and Architecture Department (DPIA) of the University of Udine. The position is fixed-term for 1 year with funding provided by the European Social Fund (ESF). 

Highlights

•

A semi-analytical model is developed for the notch tip maximum stress.

•

Application of the formula to U and blunt V-notches is demonstrated.

•

The results can be used to assess the brittle failure of notched components.

Fracture mechanics is one of the key research topics in our field (of mechanics) and has a rather rich history of innovation and applications. From earth-quakes to air-planes---the mechanics underpinning the phenomenon of materials falling apart has been essential in the development of technology.  Griffith’s work on fracture was published about a 100 years ago and is often widely regarded as the start of modern fracture mechanics.

Dear Colleagues,

The Department of Materials Science and Engineering of the Friedrich-Alexander-Universität (FAU) Erlangen-Nürnberg is inviting applications for three doctoral research positions to begin immediately. The successful applicants will work together with Prof.

Deadline for manuscript submissions: 30 November 2019.
