Homogenization methods and macro-strength of composites [PDF]

, 2001
A multi-phase periodic composite subjected to inhomogeneous shrinkage or temperature deformation and prescribed mechanical loads is considered. The asymptotic homogenisation is applied for calculation of homogenized macrostresses. A non-local approximate

Assur graphs, marginally jammed packings, and reconfigurable metamaterials

Physical Review Research, 2023
Isostatic frames are mechanical networks that are simultaneously rigid and stress-free. Isostaticity itself is a powerful concept in understanding phase transitions in soft matter and designing mechanical metamaterials.

Periodic Mechanical Stress Induces Extracellular Matrix Expression and Migration of Rat Nucleus Pulposus Cells Through Src-GIT1-ERK1/2 Signaling Pathway

Cellular Physiology and Biochemistry, 2018
Background/Aims: Periodic mechanical stress has been shown to promote extracellular matrix (ECM) synthesis and cell migration of nucleus pulposus (NP) cells, however, the mechanisms need to be fully elucidated.

Mechanical properties of ceria nanorods and nanochains; The effect of dislocations, grain-boundaries and oriented attachment [PDF]

, 2011
We predict that the presence of extended defects can reduce the mechanical strength of a ceria nanorod by 70%. Conversely, the pristine material can deform near its theoretical strength limit.

Quality factor control of mechanical resonators using variable phononic bandgap on periodic microstructures

Scientific Reports, 2022
The quality factor (Q-factor) is an important parameter for mechanical resonant sensors, and the optimal values depend on its application. Therefore, Q-factor control is essential for microelectromechanical systems (MEMS).

A novel method to design biomimetic, 3D printable stochastic scaffolds with controlled porosity for bone tissue engineering

Materials & Design, 2022
Periodic cellular materials such as body-centered cubic, face-centered cubic, and triply periodic minimal surfaces, have been used to construct scaffolds for bone tissue engineering. Their use is suboptimal for reasons like stress concentration at nodes,

Mechanical behaviour of additively manufactured elastomeric pre-buckled honeycombs under quasi-static and impact loading

Materials & Design, 2022
Selective laser sintering has been used to manufacture different structural variations of a pre-buckled circular honeycomb. The mechanical behaviour of these structures has been examined under both quasi-static and dynamic impact loading.

Entropy Change through Rayleigh-B\'enard Convective Transition with Rigid Boundaries

, 2007
The previous investigation on Rayleigh-B\'enard convection of a dilute classical gas [T. Kita: J. Phys. Soc. Jpn. {\bf 75} (2006) 124005] is extended to calculate entropy change of the convective transition with the rigid boundaries.

The periodic resin configuration design for ceramic-resin composite structure using topology optimization

International Journal for Simulation and Multidisciplinary Design Optimization, 2014
The ceramic-resin composite structure has broad prospects in many fields like rapid casting and thermal protection. Due to the coefficient of thermal expansion (CTE) of resin is about 10 times higher than that of ceramic, the excessive thermal expansion ...

Effect of heat treatment on compression properties of the 316L diamond structure fabricated through selective laser melting

Journal of Materials Research and Technology, 2023
Designing a triply periodic minimal surface (TPMS) lattice structure is a new method for lightweight. Compared with the previous foam- and strut-based structure, the TPMS lattice structure has the advantages of precise control of mechanical properties ...
