Mechanical behavior of gradient aluminum honeycomb sandwich panels

Cailiao gongcheng, 2021
Gradient aluminum honeycomb structure is an effective energy-absorbing structure. According to the concept of gradient rate, four types of aluminum honeycomb sandwich components with the same mass and different gradient rates were designed by changing ...

Flexural Behavior of 3D‐Printed Porous Bouligand‐Structured Polymers: Influence of Pitch Angle and Porosity

Advanced Engineering Materials, EarlyView.
This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

Advanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Achieving large plasticity in bulk magnesium single crystal via dynamic compression

Journal of Materials Research and Technology
Compression tests were performed on magnesium (Mg) single crystals along the c-axis at ambient temperature. The plastic behaviors under quasi-static and dynamic conditions were comparatively analyzed. Twinning dominated quasi-static compression, in which

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Controlling Grain Growth in Powder Bed Fusion of Yttria‐Stabilized Zirconia Using Femtosecond Lasers: Challenges and Methodological Insights

Advanced Engineering Materials, EarlyView.
Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

Dynamic and quasi-static lateral compression tests of ceramics tubes [PDF]

Le Journal de Physique IV, 1994
In order to investigate the deformation of ceramics tube in lateral compression, a series of experiments was carried out at dynamic and static rates. It was observed that the load and deflection when fracture occurred in dynamic tests were greater than those obtained in static tests. However, a difference between Young's moduli obtained dynamically and
