Indentation of elastically soft and plastically compressible solids [PDF]

, 2015
The effect of soft elasticity, i.e., a relatively small value of the ratio of Young's modulus to yield strength and plastic compressibility on the indentation of isotropically hardening elastic-viscoplastic solids is investigated.

Microstructural modelling of creep crack growth from a blunted crack [PDF]

, 1998
The effect of crack tip blunting on the initial stages of creep crack growth is investigated by means of a planar microstructural model in which grains are represented discretely. The actual linking-up process of discrete microcracks with the macroscopic

A Biaxial Fatigue Specimen for Uniaxial Loading [PDF]

, 2011
The aim of this paper is to present a novel un-notched fatigue test specimen in which a biaxial stress state is achieved using a uniaxial loading condition.

Simplified modelling of the behaviour of 3D-periodic structures such as aircraft heat exchangers [PDF]

, 2008
In this paper, experimental, analytical and numerical analysis are used to study and model the mechanical behaviour of a heat exchanger core consisting of a 3D-periodic structure.

Micromechanical strength effects in shock compression of solids [PDF]

AIP Conference Proceedings, 1994
Time‐resolved shock‐wave measurements and post‐shock recovery techniques have long been used as means of inferring the underlying micromechanics controlling high‐rate deformation of solids. This approach requires a considerable amount of subjective interpretation.

Viscoelectroelastic behavior of heterogeneous piezoelectric solids [PDF]

, 2000
We study the viscoelectroelastic behavior of heterogeneous piezoelectric solids, focusing on the connection between heterogeneity and coupled mechanical and electrical relaxations.

Foam Micromechanics [PDF]

, 1998
Foam evokes many different images: waves breaking at the seashore, the head on a pint of Guinness, an elegant dessert, shaving, the comfortable cushion on which you may be seated... From the mundane to the high tech, foams, emulsions, and cellular solids

A micromechanics-based nonlocal constitutive equation for elastic composites containing aligned spheroidal heterogeneities

, 2009
An explicit micromechanics-based nonlocal constitutive equation is derived that relates the ensemble averages of stress and strain for macroscopically transversely isotropic elastic composites consisting of a matrix containing a random distribution of ...

A micromechanics finite-strain constitutive model of fibrous tissue

, 2011
Biological tissues have unique mechanical properties due to the wavy fibrous collagen and elastin microstructure. In inflation, a vessel easily distends under low pressure but becomes stiffer when the fibers are straightened to take up the load.
