Modern analysis of axisymmetric shells with AQUINAS: A MATLAB finite element toolbox

SoftwareX, 2023
AQUINAS is a specialised MATLAB finite element (FE) toolbox for the nonlinear analysis of axisymmetric thin-walled shell systems, conceived by the Authors to recover a research functionality once widely available but now largely lost in the age of ...

A Novel 3D Wiring Technique—ZOLUTION Zero Degree OverLap View Universal Three DimensIONal CTO Wiring

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We present a novel simple and easy‐to‐use 3D wiring technique for coronary chronic total occlusions (CTOs) named ZOLUTION—Zero OverLap View Universal Three dimensIONal wiring. ZOLUTION can be used for: (1) Distal cap puncture, (2) CTO body wiring, (3) Retrograde wiring, and (4) Reverse controlled antegrade and retrograde tracking (reverse CART)

Programmable crack dynamics engineering enables flexible strain sensors with high linearity

FlexMat, EarlyView.
First‐decoupling theoretical framework of crack evolution elucidating the control methods, mechanistic insights, and structure‐activity relationships is established. Crack propagation from uncontrollable randomness systematically evolves into spatially ordered states.

HDQ-based solution strategy for in-plane nonlinear buckling of shallow steel arches with linear elastic supports

Frontiers in Physics
This paper investigates the in-plane nonlinear buckling of shallow steel arches with linear elastic supports. Differential equations of equilibrium are built considering a virtual work principle. To balance computational accuracy, efficiency, and cost, a

On the Birth of Isolas [PDF]

, 1982
Isolas are isolated, closed curves of solution branches of nonlinear problems. They have been observed to occur in the buckling of elastic shells, the equilibrium states of chemical reactors and other problems.

Active Metamaterials with Tunable Shear Nonreciprocity and Nonlinear Dynamics

Advanced Science, Volume 13, Issue 28, 18 May 2026.
Active gear‐based mechanical metamaterials enable simultaneous control of translational and torsional stiffnesses by 30–100×, break shear reciprocity under positive versus negative loads, broadly tune resonant frequencies, and offer programmable dynamic responses.
