This paper introduces a novel modeling approach for wood composites using concepts of numerical homogenization employed in synthetic composites. It describes multiscale model based on unit cell that incorporates both the and resin phases simulating structural composite lumber made strands. In this approach, constant thickness strand geometry, elastic properties constituents, perfect bonding between are assumed. The is composed two steps. first step estimates effective with periodic boundary...
Using the principles of classical micromechanics, analytical equations are developed in this paper to estimate effective orthotropic properties a unit cell strand-based composites according their constituent phase and microstructural features such as resin thickness, void content strand geometrical characteristics. Although special type wood composite product, Parallel Strand Lumber, is considered here an illustrative example, methodology can be used for other consisting high volume fraction...
An unconventional multi-scale approach is investigated to model interfacial damage and subsequent effects in highly filled particulate composites such as solid propellants. The basic framework by Nadot et al. (2006 Damage modelling for viscoelastic via a scale transition approach, Journal of Theoretical Applied Mechanics 44:553–583) enhanced deal with state configuration evolution under any loading. Three criteria are formulated at the microscale. first one concerns nucleation new defects,...
The design of metallic cast parts requires a compromise between the fatigue resistance component and allowable defect size due to process. Treatment sensitivity coupled with intrinsic length scales grains or other microstructure attributes is ultimately necessary form predictive basis for effects in forming growing small cracks. This work presents experimental results on high cycle behavior specimens containing surface hemispherical under uniaxial tension loading wide range notch grain...
This article deals with a non-classical scale transition devoted, in the long-run, to prediction of nonlinear mechanical behavior energetic composites. A geometrical and kinematical schematization microstructure is defined as conspicuous starting point for further localization-homogenization procedure. Thus, salient information on morphology some intraphase heterogeneity are taken into account. The first results obtained finite strain context three-dimensional periodic compared element...
The mechanical modelling of semi-crystalline polymers is highly complex due to their different micro-structural scales and some lacks regarding the understanding respective contributions crystalline amorphous phases on macroscopic behaviour. In particular, important role confined phase has be investigated. To this aim, work proposes combine full-field simulations with kinematics field measurements at same scale. material linear low density polyethylene (LLDPE), chosen for its "simple"...
A nonclassical multiscale "morphological approach" devoted to highly-filled particulate composites was proposed by Nadot et al. 1 It is extended developing complementary ingredients in order describe the evolution of damage decohesion grain/matrix interfaces. defect nucleation criterion allows number defects be followed, and a closure monitors respective proportions open closed defects. The associated with critical value current distance between two points located on both sides interface...
