“…The effective properties of each angled unit cell were estimated through the transformation matrix. A similar approach has been proposed in the literature for estimating effective properties of braided (Ayranci and Carey 2008), short fibre (Laspalas et al 2008) and woven (Sankar and Marrey 1997;Shrotriya and Sottos 2005;Vandeurzen et al 1996) composites. For panels with mixed species, a species distribution function in addition to orientation distribution function may be defined to incorporate the effect of different species.…”

A multi-scale modelling framework was developed for predicting the mechanical properties of strand-based wood composites. This framework is based on closed-form analytical models at three different resolution levels; micro-, mesoand macro-mechanical. A preprocessing step was performed to provide the input data for the three main modelling steps in this framework. Finite element-based mechanical analyses were employed to verify the accuracy of the analytical models developed for the first two steps. The predictive capability of the entire framework was validated using a set of experimental data reported in the literature. Although the methodology presented is general, it has specifically been applied here to predict an important structural property (modulus of elasticity, MOE) of a special strandbased wood composite product, namely, oriented strand board (OSB). The MOE predictions of OSB panels showed reasonable agreement with the available experimental data, thus providing confidence in the practical utility of this easy-to-

“…This represents an extension of the micromechanical models used to predict the strength of textile composites [28][29][30][31][32] The significance of including the analysis of moment terms is further illustrated in and 2-1c, the non-uniformity of applied loading leads directly to an appreciable moment term, which must be included in the analysis. In fact, in some cases it is possible that the net force resultant is zero while the effective moment resultant is non-zero, in which case conventional analysis techniques cannot be employed.…”

“…Physics-based computational models play a key role in predicting damage initiation and propagation as a result of mechanical and thermal loading conditions, simulating the interaction of elastic and electromagnetic waves with the predicted damage, and assessing the current condition of the structure. Because of the complexities associated with aerospace materials, in particular fiber-reinforced composites, damage prediction and quantification studies are often limited to two-dimensional (2D) geometries, linearly elastic constitutive models, prescribed damage initiation location and progression path, and ordered microstructures (Murthy and Chamis, 1986;Freund, 1990;Sankar and Marrey, 1997;Lee and Staszewski, 2003;Swaminathan, Ghosh, and Pagano, 2006;Skoček, Zeman, and Šejnoha, 2008). These assumptions can lead to oversimplification of the problem, and therefore, often result in poor prediction of the critical behavior of these materials.…”

Advanced aerospace materials, including fiber reinforced polymer and ceramic matrix composites, are increasingly being used in critical and demanding applications, challenging the current damage prediction, detection, and quantification methodologies.Multiscale computational models offer key advantages over traditional analysis techniques and can provide the necessary capabilities for the development of a comprehensive virtual structural health monitoring (SHM) framework. Virtual SHM has the potential to drastically improve the design and analysis of aerospace components through coupling the complementary capabilities of models able to predict the initiation and propagation of damage under a wide range of loading and environmental scenarios, simulate interrogation methods for damage detection and quantification, and assess the health of a structure. A major component of the virtual SHM framework involves having micromechanics-based multiscale composite models that can provide the elastic,
