Congratulations to Maksim Sviridenko on His First Publication in Our Group

We are pleased to announce that our article, "Dynamical simulation of origami-based elastic structures using discrete models," has been accepted for publication in Smart Materials and Structures.

The study investigates the dynamic simulation of origami-inspired structures using discrete bar-and-hinge models. Two numerical formulations are examined: an elastic approach based on extendable bar elements and a constraint-based framework employing modified SHAKE and RATTLE algorithms. The methodology is evaluated through kinematic analyses of several representative origami patterns, including Miura-ori, Kresling, and accordion Z-fold geometries, as well as through mechanical response simulations under displacement-controlled and force-controlled loading conditions.

The results demonstrate that all investigated formulations successfully reproduce the global kinematic behavior of the structures, while the constraint-based approaches provide improved agreement with analytical stiffness predictions. Among the considered methods, the SHAKE algorithm achieved the highest computational efficiency by permitting larger integration time steps, whereas RATTLE delivered comparable accuracy with additional velocity corrections. The study also provides practical recommendations for selecting appropriate numerical formulations for the dynamic analysis of origami-based systems.

This work contributes to the development of efficient computational tools for the simulation and design of deployable and morphing origami-inspired structures.
