Hard-magnetic soft materials (HMSMs) consisting of an elastomer matrix filled with high remnant magnetic particles can exhibit flexible programmability and rapid shape changing under non-contact activation, showing promising potential applications in soft robotics, biomedical devices and flexible electronics. Precise predictions of large deformations of hard-magnetic soft materials would be a key for relevant applications.

Dear iMechanicians,
Let me bring your attention what I believe is the most comprehensive study in the area of hydrogen embrittlement of additively manufactured materials. You can find all details here:
G. Álvarez, Z. Harris, K. Wada, C. Rodríguez, E. Martínez-Pañeda.
Hydrogen embrittlement susceptibility of additively manufactured Stainless Steel 316L: influence of postprocessing, printing direction, temperature and pre-straining. Additive Manufacturing 78, 103834 (2023)
One the main challenges of developing data-driven models is the data-hungry nature of Artificial Neural Networks (ANNs). In our recent paper, we introduced a data augmentation approach to expand a small original dataset without conducting extra expensive high-fidelity simulations. We then used the original and augmented datasets for developing ANN models for non-linear path dependent composites. The obtained results showed the great impact of the data augmentation approach on the accuracy of the data-driven models.
I am happy to share our paper entitled "Mechanisms of failure of aluminium-based Whipple shields under hypervelocity impact: insights from continuum simulations" published recently in Springer Nature journal Acta Mechanica.
