Problem-independent machine learning (PIML)-based topology optimization—A universal approach
Solving topology optimization problem is very computationally demanding especially when high resolution results are sought for. In the present work, a problem-independent machine learning (PIML) technique is proposed to reduce the computational time associated with finite element analysis (FEA) which constitutes the main bottleneck of the solution process.
Defect-based Physics-Informed Machine Learning Framework for Fatigue Prediction
I would like to draw your attention to our recently proposed predictive method based on a semi-empirical model (LEFM) and Neural Network, exploiting the Physics-informed Machine Learning concept. We show how the accuracy of state-of-the-art fatigue predictive models, based on defects present in materials, can be significantly boosted by accounting for additional morphological features via Physics-Informed Machine Learning.
Post-doctoral position
A post-doctoral position in the general area of material science and mechanics related to wire arc additive manufacturing (WAAM) is available in the Mechanical Engineering Department at Northeastern University, Boston, MA. The aim of the work is to investigate the thermomechanical causes of residual stresses and to assess the general build quality by experimental and modeling approaches. FLIR and other non-contact measurement techniques will be used for in-situ process monitoring. XRD will be used to assess residual stresses.

Article: An Atomistic-based Finite Deformation Continuum Membrane Model for Monolayer Transition Metal Dichalcogenides
Highlights
• A finite-deformation crystal-elastic membrane model for TMD monolayers is presented.
• Strains of the middle surface and two normal-stretches describe the deformation.
• The continuum hyperelastic strain energy is obtained from an interatomic potential.
• The present model matches well with the purely atomistic simulations.
