Optimization of non periodic homogenized microstructures [PDF]
ESAIM: Proceedings, 1997 The authors define a microstructure by means of homogenized equations. The model of homogenized microstructure is applied to maximize the mechanical resistance in the case of torsion of a bar. Such a criterion is proved to be differentiable. An explicit procedure is presented to compute the corresponding differential, and the result is used to ...

Modeling of static recrystallization kinetics by coupling crystal plasticity fem and multiphase field calculations [PDF]
Computer Methods in Materials Science, 2013 In multi-step hot forming processes, static recrystallization (SRX), which occurs in interpass times, influences the microstructure evolution, the flow stress and the final product properties.

Pulsar Microstructure Quasi-Periodicity [PDF]
Symposium - International Astronomical Union, 1981 Microstructure in pulsars occasionally has a quasi-periodic character with an average period of around 0.9 ms. A survey of this little known phenomenon (time characteristics, polarization, frequency behaviour, etc.) together with some new results are presented. Some physical interpretations (e.g.

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).

Extremely Emissive V-Grooved Microstructure Made of SU-8 for Enhanced Radiative Cooling
IEEE Photonics Journal, 2023 For a structure to show radiative cooling property, it must have first, high reflectivity of above 90% in the wavelength range of 0.3 to 3 μm, and second, high emissivity for the wavelengths ranging from 8 to 13 μm, namely ...

Bloch spectral analysis in the class of non-periodic laminates [PDF]
ITM Web of Conferences, 2022 In this work, we introduce Bloch waves to study the homogenization process in a class of simple laminates which are obtained as a particular Hashin-Shtrikman microstructure involving translations and dilations in only one direction. This makes this class

Peridynamic Modelling of Periodic Microstructured Materials [PDF]
Procedia Structural Integrity, 2020 With the enhancement in additive manufacturing technology, microstructured materials has attracted significant attention during the last few years. Although these materials can show homogenised properties at the macroscopic scale, their microstructural properties can be very influential on the overall material behaviour especially on the fracture ...

Effective Maxwell’s equations in general periodic microstructures [PDF]
Applicable Analysis, 2017 We study the time harmonic Maxwell equations in a meta-material consisting of perfect conductors and void space. The meta-material is assumed to be periodic with period η > 0; we study the behaviour of solutions ( E^η ,H^η ) in the limit η → 0 and derive an effective system.
