a unit cell, full finite element meso model, and a mosaic macro model are developed to simulate the elastic and damage progression behaviour of the two weave types.
In this paper we develop a domain decomposition method (DDM), based on the discontinuous Galerkin (DG) and the local discontinuous Galerkin (LDG) methods, for solving multiscale problems involving macro sub-domains, where a macro model is valid, and micro sub-domains, where the macro model is not valid and a more costly micro model must be used.
A significant feature of IDARC to implement inelastic behavior in the macro model is to apply a distributed plasticity model with a flexibility matrix approach instead of the hinge model developed for steel frames.
A general equilibrium macro model is used to simulate trade reform scenarios and estimate their price effects, while a micro module maps these price changes into real income changes at the individual household level.
The macro model is taken as the Euler equations for the gas dynamics problem and as a hydrodynamic model and a high field model for the semiconductor device problem.
In our method, the individual molecular solvers, which provide information to the macro model, are not coupled with the continuum grid at nodes (i.e. point-wise coupling), instead coupling occurs over distributed heterogeneous fields (here referred to as field-wise coupling).
A macro-model was also developed to further investigate progressive collapse in three dimensions.
For verification, the proposed macro-model was applied to existing isolated and coupled wall specimens subjected to cyclic loading.
The macro-model was idealized with multiple longitudinal uniaxial elements of concrete and re-bar to describe the flexure- compression responses of walls.
For verification, the proposed macro-model was applied to existing slender, low-rise, and coupled wall specimens subjected to cyclic loading.
