Biography

Alejandro Mota is a Principal Member of the Technical Staff in the Mechanics of Materials Department at Sandia National Laboratories in Livermore, California. He develops computational methods, constitutive models, and open-source software for finite-deformation solid mechanics, with emphasis on fracture and damage, strain localization, contact, and multiscale and multiphysics coupling. Applications of his work range from high-velocity impact and traumatic injury biomechanics to permafrost degradation and coastal erosion in the Arctic. A common thread is carrying methods from formulation to production, so that analysts can use them in Sandia’s engineering codes.

He leads the Schwarz alternating method research thread at Sandia, which uses the method as a single framework for concurrent multiscale coupling, contact in elastodynamics, and the coupling of full-order finite element models with reduced-order and data-driven models for predictive digital twins. That line of research, begun in 2015, is now a native overlapping and non-overlapping coupling capability of the Sierra/SM production code. He co-leads the Arctic Coastal Erosion (ACE) model, a thermo-mechanical finite element framework for permafrost degradation and episodic block failure that has been calibrated and validated against field observations at Drew Point, Alaska, and he developed its finite-deformation cap plasticity model for permafrost, calibrated against triaxial data on frozen sand. With the University of California, Irvine, he formulated mesh improvement as a pseudo-strain energy minimization, which is being carried into the Sierra and Cubit tool chains.

He is the main developer and maintainer of LCM (Albany-LCM), the principal author of Norma.jl, the creator of its GPU-native successor Carina.jl, and the original author of the MiniTensor library in Trilinos, which is used by both research and production solid mechanics codes at Sandia. Before joining Sandia in 2007 he was a postdoctoral scholar and then a staff scientist at the California Institute of Technology, where he worked on fracture and fragmentation under high-speed impact, and he practiced as a structural engineer in Mexico. He holds a Ph.D. in Structural Engineering, with a concentration in Theoretical and Applied Mechanics, from Cornell University.

  • LCM (Albany-LCM), main developer and maintainer since 2010. Open-source parallel implicit C++ finite element code for solid mechanics and thermo-mechanics, built on Albany and Trilinos. Home of the Arctic Coastal Erosion model; maintained on the current Trilinos stack with continuous integration on GitHub. https://github.com/sandialabs/LCM
  • Carina.jl, creator and principal author. GPU-native finite element framework in Julia for coupled multiphysics that runs quasi-static, implicit dynamic, and explicit dynamic solid mechanics on CPUs and NVIDIA and AMD GPUs from one source, with Krylov, algebraic multigrid, quasi-Newton, and matrix-free solvers. https://github.com/Cthonios/Carina.jl
  • Norma.jl, principal author. Open-source Julia testbed for coupling and multiphysics in solid mechanics and heat conduction: Schwarz coupling with impedance and Robin transmission conditions, Aitken acceleration, subcycling, operator-inference reduced-order models with mid-run model and mesh swapping, and a three-field Hu-Washizu element. https://github.com/sandialabs/Norma.jl
