<p>Multiscale and multiphysics problems need novel numerical methods in order for them to be solved correctly and predictively. To that end, we develop a wavelet based technique to solve a coupled system of nonlinear partial differential equations (PDEs) while resolving features on a wide range of spatial and temporal scales. The algorithm exploits the multiresolution nature of wavelet basis functions to solve initial-boundary value problems on finite domains with a sparse multiresolution spatial discretization. By leveraging wavelet theory and embedding a predictor-corrector procedure within the time advancement loop, we dynamically adapt the computational grid and maintain accuracy of the solutions of the PDEs as they evolve. Consequently, our method provides high fidelity simulations with significant data compression. We present verification of the algorithm and demonstrate its capabilities by modeling high-strain rate damage nucleation and propagation in nonlinear solids using a novel Eulerian-Lagrangian continuum framework.</p>

<p><span>We present a novel image-based multiscale multigrid solver that can efficiently address the computational complexity associated with highly heterogeneous systems. This solver is developed based on an image-based, multiresolution model that enables reliable data flow between corresponding computational grids and provides large data compression. A set of inter-grid operators is constructed based on the microstructural data which remedies the issue of missing coarse grid information. Moreover, we develop an image-based multiscale preconditioner from the multiscale coarse images which does not traverse through any intermediate grid levels and thus leads to a faster solution process. Finally, an image-based reduced order model is designed by prolongating the coarse-scale solution to approximate the fine-scale one with improved accuracy. The numerical robustness and efficiency of this image-based computational framework is demonstrated on a two-dimensional example with high degrees of data heterogeneity and geometrical complexity.</span></p>

<p class="MsoNormal">Computational methods including AI are revolutionizing the materials design world. Today, an engineer or scientist can simply enter the desired properties into a program and the system will manufacture a microstructure that matches the specifications. Algorithms predict which chemical building blocks at the nanoscale can be combined to create advanced materials with superior functions — from ultra-strong, lightweight materials used in the automotive, construction and aerospace industries, to biomaterials used in implants and biomedical devices with the ability to self-heal and regenerate. The goal of this new approach is to construct, in a bottom-up manner, atomically-precise products through the use of molecular design and manufacturing, allowing the fabrication a vast array of designs.</p>
<p class="MsoNormal">Participants will spend a week at MIT and immerse themselves in interactive lectures, labs and networking with others. Participants will receive an MIT certificate upon successful completion. </p>
<p class="MsoNormal">The course covers a variety of topics from theory, modeling and experimental perspectives, including the use of machine learning and artificial intelligence for materials design, additive manufacturing, as well as translational components to connect disparate domains in materials science and engineering.</p>

We describe important material characterization techniques using numerous methods of spectroscopy and microscopy. We detail numerous multi-scale computational modeling techniques that complements these experimental techniques: DFT at the atomistic scale; fully atomistic and coarse-grain molecular dynamics at the molecular to mesoscale; continuum modeling at the macroscale. Additionally, we present case studies that utilize experimental and computational approaches in an integrated manner to broaden our understanding of the properties of two-dimensional materials and materials based on silk and silk-elastin-like proteins.</span></span></span></p>

<p>Abstract</p>
<p>The bowing of edge dislocations from a row of collinear obstacles in Al is studied using concurrent atomistic-continuum simulations of submicron-sized realizations containing up to 238 million atoms. Results show that (1) as the number of adjacent bowed-out dislocation segments increases, the critical dislocation depinning stress approaches that for an infinite array of obstacles and (2) for the unstable overall semi-elliptic dislocation configuration, the presence of intermediate obstacles reduces the dislocation half-loop height, but doesn't affect the critical shear stress. Our work highlights the significance of the effects of adjacent bowed-out segments on cooperative dislocation bow-out.</p>

A general macroscopic modeling framework is developed and then a simplified macroscopic model is derived. The model incorporates Asymptotic Numerical Method (ANM) as a robust path-following technique to trace the post-buckling evolution path and to predict secondary bifurcations. The proposed multi-scale finite element framework allows sinusoidal and square checkerboard patterns as well as their bifurcation portraits to be described from a quantitative standpoint. Moreover, it provides an efficient way to compute large-scale instability problems with a significant reduction of computational cost compared to full models.</p>

<p><strong>Abstract:</strong></p>
<p>Bridging techniques between microscopic and macroscopic models are discussed in the case of wrinkling analysis. The considered macroscopic models are related to envelope equations of Ginzburg−Landau type, but generally, they are not valid up to the boundary. To this end, a multi-scale approach is considered: the reduced model is implemented in the bulk while the full model is applied near the boundary and these two models are coupled with the Arlequin method (Ben Dhia, 1998). This paper focuses on the definition of the coupling model and the transition between two scales. Especially, a new nonlocal bridging technique is presented and compared with another recent one (Hu et al., 2011). The present method can also be seen as a guide for coupling techniques involving other reduced order models.</p>

Dear Colleagues,
</p>
<p>
</p>
<p>
The submission deadline for abstracts to the 17th U.S. National Congress on Theoretical & Applied Mechanics has been extended to Jan 6th, 2014. Please consider submitting an abstract to at the website below. We will be holding a symposium on "Elasticity, PLasticity, and Multiphysics of Hierarchical Materials: Mechanisms to Mechanics" that many of you should find quite interesting!

"Advances in materials synthesis and characterization techniques together with ever increasing sophistication of computational prowess has enabled concerted efforts toward design and development of materials with novel architectures such ranging from hierarchical composites to designer nano-micro lattice structures. The key idea is to modulate functional characteristics through microstructural engineering for a variety of applications that include, but are not limited to, materials used in structural, biological, thermal, electrical, optical and electronic systems.
</p>
<p>
</p>
<p>
The goal of this symposium is to provide a platform to discuss exciting progress and challenging questions in the area of hierarchical materials. It aims at understanding the mechanics issues related to elastic and inelastic behaviors of a wide range of hierarchical microstructures such as nano-scaled metals, hybrid composites, fibrous architectures, lattice structures. Of particular interest is gaining insight into the mechanisms-mechanics nexus that would enable translating principal deformation mechanisms in these material systems into physically sound constitutive frameworks that enable optimal design. We further invite contributions highlighting the multiscale and multiphysics nature arising from the coupling of the above mechanical phenomena to thermal, electrical, chemical, or physical stimuli.
</p>
<p>
</p>
<p>
The symposium strongly encourages contributions from the experimental and modeling perspectives at multiple length-scales and <span>time-scales."</span><span> </span>
