TL;DR

This paper proposes an origami-inspired cellular cushion material based on the Kresling pattern, which achieves high energy absorption efficiency (~70%) and dissipation (94%) through controlled folding and viscoelastic damping. The design enables full shape recovery, damage resistance, and tunable mechanical response via advanced manufacturing, overcoming limitations of conventional foam-based materials that suffer from force fluctuations and permanent deformation.

ABSTRACT

Current architectured cellular cushion materials rely mainly on damage and/or unpredictable collapse of their unit cells to absorb and dissipate energy under impact. This prevents shape recovery and produces undesirable force fluctuations that limit reusability and reduce energy absorption efficiency. Here, we propose to combine advanced manufacturing technologies with Origami principles to create a new class of architectured cellular viscoelastic cushion material which combines low weight and high energy absorption efficiency with damage resistance and full behavior customization. Each unit cell in the proposed material is inspired by the Kresling Origami topology, which absorbs impact energy by gracefully folding the different interfaces forming the cell to create axial and rotational motions. A large part of the absorbed energy is then dissipated through viscoelasticity and friction between the interfaces. The result is a nearly ideal cushion material exhibiting high energy absorbing efficiency (around 70%) combined with high energy dissipation (94% of the absorbed energy). The material is also tunable for optimal performance, reliable despite successive impact events, and achieves full shape recovery.

Motivation & Objective

• To address the limitations of conventional cellular cushion materials, which rely on irreversible damage and exhibit force fluctuations during impact.
• To develop a lightweight, reusable cushion material with high energy absorption efficiency and damage resistance.
• To leverage origami principles and advanced manufacturing to achieve tunable, predictable, and repeatable mechanical behavior under impact.
• To create a material that combines axial and rotational deformation with viscoelastic damping for superior energy dissipation.
• To enable full shape recovery after multiple impact events, enhancing reusability and performance consistency.

Proposed method

• The unit cell is designed based on the Kresling origami topology, enabling controlled folding under compression to generate axial and rotational motion.
• The material is fabricated using advanced manufacturing techniques (e.g., 3D printing) to ensure geometric precision and reproducibility.
• A finite element model using Abaqus simulates quasi-static behavior with shell elements, accounting for 3D translation, rotation, and in-plane/out-of-plane deformations.
• Boundary conditions restrict rotation at every other junction and prevent overturning to avoid numerical artifacts and ensure stable simulation.
• Uniaxial quasi-static testing is performed using an Instron 5960 machine at 0.15 mm/s displacement rate to generate F-δ curves.
• Impact testing uses a free-falling impactor with laser and force sensors at 20 kHz sampling rate to measure force-time, deflection-time, and force-deflection responses.
