We use molecular dynamics, dislocation dynamics, crystal plasticity, and finite element methods, alone and coupled across length scales, to predict how defects control the strength and deformation of metallic materials.

About
Simulation-driven design of stronger metals
Ioannis Mastorakos is an Associate Professor in the Department of Mechanical and Aerospace Engineering at Clarkson University and, since July 2026, the MAE Program Lead. He received a B.Sc. in Physics (1994) and a Ph.D. in Engineering (2004) from Aristotle University of Thessaloniki, Greece, and worked as a consultant at Hyperco in Thessaloniki from 2002 to 2004.
In 2004 he joined the School of Mechanical and Materials Engineering at Washington State University as a Research Associate, later serving as Visiting Assistant Professor (2008) and Clinical Assistant Professor (2011). He joined Clarkson in 2014 as an Assistant Professor and was promoted to Associate Professor in 2020. His group studies plasticity in high-entropy alloys, polycrystals, and nanostructured metals, combining atomistic and mesoscale simulations with machine-learning surrogates and experimental validation.
Professional service. TMS Composite Materials Committee: Secretary (2019–2022), Vice-Chair (2022–2024), Chair (2024–2026), and currently JOM Advisor; member of the TMS Awards Committee (2020–2023) and JOM topic editor (2023). Co-editor of Composite Materials: Sustainable and Eco-Friendly Materials and Applications (TMS/Springer, 2024). Symposium organizer at Materials Science & Technology (MS&T) 2017 and 2020 and the International Conference on Plasticity 2011, and organizer of four symposia at the TMS Annual Meetings (2023–2026): three on eco-friendly composite materials and one on additive manufacturing of composite metallic materials, and member of the organizing committees of four international and national conferences. Proposal reviewer for NSF and for the DOE Nuclear Energy University Program and Basic Energy Sciences. Journal reviewer, with 65 manuscript reviews since 2018 (Web of Science), for Scripta Materialia, Modelling and Simulation in Materials Science and Engineering, Journal of Nuclear Materials, Journal of Engineering Materials and Technology, and others. Member of ASME, MRS, and TMS.
Research Areas
What we study
High-Entropy Alloys
Nanoindentation simulations of incipient plasticity, and deformation and failure of additively manufactured AlCoCrFeNi alloys.
Dislocation Dynamics & Crystal Plasticity
FFT-based crystal plasticity coupled with continuum dislocation dynamics (EVPFFT-CDD) to link dislocation patterning to hardening.
Machine-Learning Surrogates
Neural operator models that predict full-field stress, strain, and dislocation density evolution at a fraction of the solver cost.
Nanofoams & Nanoscale Multilayers
Ligament- and interface-controlled strength of Cu/Ni nanofoams, nanolaminates, and core-shell nanowires.
