Dear colleagues,
We invite you to read our recent article, which proposes a multiband homogenization scheme and has been accepted to appear in JMPS (https://www.sciencedirect.com/science/article/pii/S002250962200182X)
Multiband homogenization of metamaterials in real-space: Higher-order nonlocal models and scattering at external surfaces
For students who are attending IMECE this year, there is a wonderful opportunity for you to apply for a travel award ($1000/grad, $500/under). There are a total of 50 travel awards for you to claim. You also have a possibility to win cash awards ($2000 total). You need to submit a poster abstract by 6/29. See https://event.asme.org/IMECE/Program/NSF for more details.
Dear colleagues,
I would like to draw your attention to a recent work we have been doing to set up a library of examples of discrete one-sided contact problems with Coulomb friction.
The collection of problems can be found here https://github.com/FrictionalContactLibrary/fclib-library and the C API for writing and listing these files here:
In linear elasticity, universal displacements for a given symmetry class are those displacements that can be maintained by only applying boundary tractions (no body forces) and for arbitrary elastic constants in the symmetry class. In a previous work, we showed that the larger the symmetry group, the larger the space of universal displacements. Here, we generalize these ideas to the case of anelasticity. In linear anelasticity, the total strain is additively decomposed into elastic strain and anelastic strain, often referred to as an eigenstrain.

Most 4D printings utilize 1D structural deformation — bending and coiling to morph a flat shape by controlling only a single curvature, limiting the realization of complex 3D curved surfaces with two curvatures. We quantitatively analyze the morphing of a 2D plate into doubly curved surfaces on a direct 4D printing of a single isotropic material employing anisotropy of shape memory effect during the extrusion-based printing.
In this work, a new mixed finite element formulation is presented for the analysis of two-dimensional compressible solids in finite strain regime. A three-field Hu-Washizu functional, with displacement, displacement gradient and stress tensor considered as independent fields, is utilized to develop the formulation in spatial configuration. Certain constraints are imposed on displacement gradient and stress tensor so that they satisfy the required continuity conditions across the boundary of elements.
