Multi–scale modelling of timber–frame structures under seismic loads [PDF]
This paper introduces a versatile hysteretic constitutive law, developed for various joints with steel fasteners commonly used in timber structures (nails, screws, staples, 3D connectors of bracket type, punched plates). Compared to previous

Ultrafast Adhesion/Friction Bidirectionally Switchable Control by Vibration
Bioinspired gradient smooth architectures enable vibration‐switchable adhesion/friction with 62.02 kPa adhesion strength, 131.57 kPa shear strength, tilt angles ≥ 3°, roughness ≥ Ra 0.8 µm, 400 Hz antivibration robustness, and dual‐mode control. The synergy of geometry optimization and vibration modulation tuning bridges multidomain adaptability and ...

This paper investigates the degradation of pointing accuracy in the Kunming 40‐m radio telescope due to long‐term equipment aging and environmental disturbances. Conventional linear pointing models are constrained by their linear modeling framework, making it difficult to accurately represent the nonlinear errors induced by temperature, wind speed, and

ABSTRACT We propose a unified constitutive framework for two irreversible processes governing coupled flow and geomechanics in porous media: capillary hysteresis in two‐phase flow and elastoplastic deformation. Extending our previous work that draws an analogy between capillary hysteresis and elastoplasticity theory, we introduce an additive ...

On the Spontaneous Identity of Chiral and Super Symmetry Breaking in Pure Super Yang Mills Theories
We show that in supersymmetric pure Yang Mills theories with arbitrary simple gauge group, the spontaneous breaking of chiral fermionic and bosonic charge by the associated gaugino and gauge boson condensates implies the spontaneous breaking of ...

Fatigue‐Resistant Mechanoresponsive Color‐Changing Hydrogels for Vision‐Based Tactile Robots
Mechanoresponsive color‐changing materials that can reversibly and resiliently change color in response to stress are highly desirable for diverse technologies in optics, sensors, and robots; however, such materials are rarely achieved. This work reports a fatigue‐resistant mechanoresponsive color‐changing hydrogel that exhibits reversible, resilient ...

A stochastic approach for deriving effective linear properties of bilinear hysteretic systems subject to design spectrum compatible strong ground motions [PDF]
A novel statistical linearization based approach is proposed to derive effective linear properties (ELPs), namely damping ratio and natural frequency, for bilinear hysteretic oscillators subject to seismic excitations specified by an elastic response ...
