Please check our new article on beam to surface contact modeling, recently accepted in  Computer Methods in Applied Mechanics and Engineering: https://doi.org/10.1016/j.cma.2020.113275 . We have used a previously reported dynamic corotational formulation and added frictional contact terms, which provide a fully consistent formulation.

The synergic combination of smart soft composites with kirigami/origami principles leads to self-deployable systems. To date, the development of soft deployable structures has largely been an empirical process. Focusing on the recently developed shape memory alloy (SMA)-based soft deployable structures, this paper describes an analytical model and a finite element (FE) numerical scheme to investigate deformation and deployment performance of this system.

Composites Design and Manufacturing HUB (cdmHUB) invites you to attend the Global Composites Experts Webinar series. The goal of the series is to accumulate the vast knowledge of composites that has been developed over the past 50 years and to make it available to the global composites community. The inaugural lecture entitled Digital Disruption of Composites Manufacturing and Design will be given by Prof. Anoush Poursartip on September 3rd 11am-12pm EDT. Please visit https://lnkd.in/g9mkRjk for more details.

We propose a new layered configuration of isotropic tubes that twists upon inflation, based on the concept of geometric incompatibilities. For more details click "Read more" below. The full paper can be found at: https://doi.org/10.1115/1.4047980.

Hello Dear All,

    Thanks to Extreme Mechanics Letter, a new discusion of localized plastic deformation was published there. Three outlines of our work are:

      1. A new dislocation based consitutive model is built. It has a concise mathematical struture.

      2. Heat generated by plastic energy can be calculated by a mechanical version of Joule's law.

      3. Shear band and neck locations can be predicted by the mathematical model.

We calculate bending moduli along the principal directions for forty-four select atomic monolayers using ab initio density functional theory (DFT). Specifically, considering representative materials from each of Groups IV, III–V, V monolayers, Group IV monochalcogenides, transition metal trichalcogenides, transition metal dichalcogenides and Group III monochalcogenides, we utilize the recently developed Cyclic DFT method to calculate the bending moduli in the practically relevant but previously intractable low-curvature limit.
