In this paper we will review and extend the results of [21], which covered the case of 3D thermo-piezoelectric polycrystals. In that context the settings of conductivity, elasticity, pyroelectricity, piezoelectricity, thermo-electricity and thermo-elasticity can be viewed as particular cases. We will consider a class of composites more general than polycrystals, where the set of allowable mater...

Sonoelastography is the visualisation of elastic properties using ultrasound. It can enable tumours to be detected and localised based on their elasticity when they are less elastic than the surrounding soft tissue. In vibration sonoelastography the target tissues are vibrated while simultaneously recording ultrasound images. A technique for imaging relative elastic properties is proposed that ...

The shear lag model has been used in conjunction with the 3D elasticity equations to determine the stress state in a fiber/matrix system containing an interface crack. The use of a shear lag model to capture the stress state at the crack tip and the modelling of the region away from the crack tip by the elasticity equations leads to a simple analytical expression which can be used to determine ...

Thermoplastic vulcanizate (TPV) combines the high elasticity of elastomers and excellent processability of thermoplastics. Novel bio-based TPV based on poly (lactide) (PLA) and poly (1,4-butanediol/2,3-butanediol/succinate/itaconic acid) (PBBSI) were prepared in this research. PBBSI copolyesters were synthesized by melting polycondensation, and the molecular weights, chemical structures and com...

Invasion of cancer cells into the extracellular matrix (ECM) is a key step in tumor infiltration and metastasis. While the strong influence of ECM stiffness in governing tumor cell migration has been well established in two-dimensional culture paradigms, investigation of this parameter in three-dimensional (3D) ECMs has proven considerably more challenging, in part because perturbations that ch...

This paper tracks the development of lattice models that aim to describe linear elasticity solids and field equations which converge asymptotically toward those isotropic continua, thus showing connection between discrete continuum. In 1759, Lagrange used strings/rod dynamics show link mixed differential-difference equation a one-dimensional (1D) partial differential associated A consistent thr...

The accurate prediction of the thermomechanical properties newly developed polymer composites is important in determination their possible areas application. In this study, a 3D model representative volume element (RVE) with different wood flour weight ratios (5, 10, 15, 20, 25 and 30 %) was used to develop composites. Micromechanical material modelling software (Digimat) conjunction finite ana...
