Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing

Advanced Science, EarlyView.
Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...

ANTI-VIBRATION INSULATION POSSIBILITIES OF THE OVERGROUND PARKING OVER THE DAMBOVITA RIVER. ANTISEISMIC PROTECTION SYSTEMS [PDF]

Analele Universităţii "Constantin Brâncuşi" din Târgu Jiu: Seria Inginerie, 2019
Too strong an excitation force cannot be applied to a resonant system, because it will develop vibrations of very large amplitudes. The damping is the one that controls the motion of a resonant system at its natural frequency.

Flow Mode Magnetorheological Dampers with an Eccentric Gap

Advances in Mechanical Engineering, 2014
This paper analyzes flow mode magnetorheological (MR) dampers with an eccentric annular gap (i.e., a nonuniform annular gap). To this end, an MR damper analysis for an eccentric annular gap is constructed based on approximating the eccentric annular gap ...

Compact Tabletop Magnetic Resonance Elastography for Mapping Soft Tissue Viscoelasticity

Advanced Science, EarlyView.
This work introduces a compact, low‐cost tabletop magnetic resonance elastography platform for high‐resolution viscoelastic mapping in soft‐tissue specimens. Using this method in human colorectal liver metastases, we demonstrate fully automated biomechanical profiling of treatment response and show that heterogeneity‐based metrics outperform ...

Chemically Programmable Underwater Sound‐Absorbing Metamaterial via MXene Self‐Assembly

Advanced Science, EarlyView.
MXene self‐assembly creates a chemically programmable underwater metamaterial with quasi‐periodic layers and a chemical‐physical multi‐level constraint system. A crosslinker as a ‘chemical scissor’ precisely edits microscopic interactions, exciting deep‐subwavelength strong local resonances that induce near‐zero/negative effective bulk modulus (Keff ...
