Abstract A new two-dimensional nanomaterial—Titanium Carbide MXene (Ti 3 C 2 -MXene)—was reported in 2011. In this work, the microscale models of Ti -MXene nanomaterial are considered with polymer matrix. The nanocomposites modeled using nacre-mimetic brick-and-mortar assembly configurations due to enhanced mechanical properties and interlocking mechanism between (brick) matrices (mortar). matr...

Abstract Under multi-wheel heavy load, the asphalt mixture is prone to exhibit deformation superposition effect, which exacerbates damage of pavement structure. Multi-point penetration tests and numerical simulations by discrete element method (DEM) are performed investigate effect micromechanical characteristics mixture. The wheel spacing, group, evolution behavior analyzed. Results indicate t...

Micromechanical resonators with fundamental vibrational mode frequencies in the range 10MHz–1GHz can now be fabricated [1, 2]. Applications include fast, ultrasensitive force and displacement detectors [3], electrometers [4, 5], and radio frequency signal processors [6]. However, the advances in the development of micromechanical devices also raise the fundamental question of whether mechanical...

Because of their high surface over volume ratio, the mechanical behavior of micrometer sized structures differs from that of usual macroscopic objects. Their surface plays a key role, and this property has been proposed to devise micromechanical sensors of environmental changes [1]. In particular, a significant effort has been put on the development of biological sensors [2], thus highlighting ...

A new contact bond model based on the Mohr-Coulomb failure criterion has been implemented in PFC2D to reproduce the behaviour of frictional cohesive (c, φ) geomaterials. According to this model, the bond strength can be clearly divided into two distinct micromechanical contributions: an intergranular friction angle and a cohesive bond force. A parametric analysis has been run to validate the pr...

The present work deals with crystal plasticity of single crystal nickel-base superalloys. In this context, a scale transition of transferring information from mesoscale towards a physically justified micromechanical model is shown. A numerical coupling between dislocation dynamic simulations and the finite element method, the socalled Discrete-Continuous Model (DCM) is used in order to take int...

In the last decades, the class of Ti-rich TiAl-based intermetallic materials has replaced many contemporary alloys till 900 °C. Due to higher oxidation resistance, 20% lower density and higher (about 150 °C more) operating temperature possibility of Al-rich TiAl alloys over Ti-rich side, phases from the Al-rich region of this alloy system are considered to be highly potential candidates for hig...
