Full‐scale Shaking Table Tests on a 10‐story Steel Moment‐resisting Frame Building with Buckling‐restrained Braces

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2356-2378, August 2026.
ABSTRACT In February 2023, a comprehensive series of shaking table tests were conducted at the E‐Defense facility, the world's largest three‐dimensional earthquake simulator, on a full‐scale 10‐story steel moment‐resisting frame supplemented with BRBs.

When creation and capture diverge: Why breakthrough inventions do not break through alike

open access: yesStrategic Management Journal, Volume 47, Issue 8, Page 2177-2207, August 2026.
Abstract Reserch Summary Breakthrough inventions are central to firms' competitive advantage, yet what constitutes a breakthrough remains unclear. We examine the relationship between technological quality (measured by forward citations) and economic value (measured by grant‐day abnormal stock‐returns) of patents. Using U.S. patents assigned to publicly

A Contribution to the Debate on Methods to Determine ΔKth in a Conservative Way

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 8, Page 3542-3553, August 2026.
ABSTRACT The threshold value for fatigue crack growth ΔKth is considered to be the most important value in the context of damage tolerant design. Therefore, a reliable experimental determination of the threshold value is of great interest. However, it has been shown several times that the standardized approach can lead to non‐conservative values ...

A Hybrid‐High Order Method for Fracture Modelling

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 13, 15 July 2026.
ABSTRACT In this work we introduce a new Hybrid High‐Order method for the numerical simulation of fracture propagation based on phase‐field models. The proposed method: supports general meshes made of polygonal/polyhedral elements, which provides great flexibility in mesh design and adaptation; can accommodate large variations of both the displacement ...

Generalised Phase Field Modelling of Fracture in Gyroid Structures: Numerical and Experimental Insights Using Additively Manufactured Polylactic Acid (PLA) Specimens

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 13, 15 July 2026.
ABSTRACT This study presents a three‐dimensional cohesive phase field framework for simulating quasi‐static fracture in Gyroid lattice structures. To the authors' knowledge, this is one of the first experimentally validated applications of a diffuse cohesive phase field model to describe damage and fracture evolution in additively manufactured ...
