Theoretical model of homogenized piezoelectric materials with small non-collinear periodic cracks [PDF]
Fracture and Structural Integrity, 2017 An analytical model for the homogenization of a piezoelectric material with small periodic fissures is proposed on the basis of the method of asymptotic expansions for the elastic displacement, the electric scalar potential and the test functions ...

Influence of Uniaxial Tensile Stress on the Mechanical and Piezoelectric Properties of Short-period Ferroelectric Superlattice [PDF]
Nanoscale Research Letters, 2009 Tetragonal ferroelectric/ferroelectric BaTiO3/PbTiO3 superlattice under uniaxial tensile stress along the c axis is investigated from first principles. We show that the calculated ideal tensile strength is 6.85 GPa and that the superlattice under the loading of uniaxial tensile stress becomes soft along the nonpolar axes.

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.

A modified Oster-Murray-Harris mechanical model of morphogenesis [PDF]
, 2013 There are two main modeling paradigms for biological pattern formation in developmental biology: chemical prepattern models and cell aggregation models. This paper focuses on an example of a cell aggregation model, the mechanical model developed by Oster,

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).

Meso-scale modelling of 3D woven composite T-joints with weave variations [PDF]
, 2019 A meso-scale modelling framework is proposed to simulate the 3D woven fibre architectures and the mechanical performance of the composite T-joints, subjected to quasi-static tensile pull-off loading. The proposed method starts with building the realistic

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 ...
