Contact mechanics based solution to predict modulus of asphalt materials with high porosities
Materials & Design, 2021 Asphalt mixtures with high porosities (known as porous asphalt (PA) mixes) are becoming a popular choice among road authorities as it provides better skid resistance while also reducing tire-pavement noises.

Micromechanical Modelling of Size Effects in Microforming
Procedia Engineering, 2017 Abstract This paper deals with the micromechanical modelling of the size dependent mechanical response of polycrystalline metallic materials at micron scale through a strain gradient crystal plasticity framework. The model is implemented into a Finite Element software as a coupled implicit user element subroutine where the plastic slip and ...

Strongly coupled modes in a weakly driven micromechanical resonator
, 2012 We demonstrate strong coupling between the flexural vibration modes of a clamped-clamped micromechanical resonator vibrating at low amplitudes. This coupling enables the direct measurement of the frequency response via amplitude- and phase modulation ...

Micromechanical modeling of ferroelectric films
Journal of Materials Research, 2005 Ferroelectric films are growing in significance as non-volatile memory devices, sensors, and microactuators. The stress state of the film, induced by processing or constraints such as the substrate, strongly affects device behavior. Thus, it is important to be able to model the coupled and constrained behavior of film material.
