Distorting crack-front geometry for enhanced toughness by manipulating bioinspired heterogeneity by Kaijin Wu, Zhaoqiang Song, Mengqi Liu, Zewen Wang, Si-Ming Chen, Shu-Hong Yu, Linghui He, Yong Ni

“…We reveal theoretically and demonstrate experimentally that the local mixed-mode I + II + III fracture triggered by local anisotropic heterogeneities lead to a helical crack front in a representative heterogeneous system with bioinspired twisted plywood structures under remote mode I loading. An anomalous nonlinear law of both the enhanced fracture resistance and the helical crack-front length versus the microstructural orientation is revealed, in contrast to the linear toughening law ignoring the hidden 3D topography within crack fronts. …”

Robust and Sparse Kernel-Free Quadratic Surface LSR via L_2,p-Norm With Feature Selection for Multi-Class Image Classification by Yongqi Zhu, Zhixia Yang, Junyou Ye, Yongxing Hu

“…In this study, a framework approach is introduced for the multi-classification problem based on the <inline-formula> <tex-math notation="LaTeX">$L_{2,p}$ </tex-math></inline-formula>-norm, utilizing more general loss functions and regularization terms, which is a robust sparse kernel-free quadratic surface least squares regression (RSQSLSR). The nonlinear relationship between features is addressed using a quadratic kernel-free technique combined with <inline-formula> <tex-math notation="LaTeX">$\epsilon $ </tex-math></inline-formula>-dragging technology and manifold regularization to learn soft labels, which can achieve the goal of feature selection and classification, simultaneously. …”
