Advanced Engineering Materials, EarlyView.Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...

Advanced Engineering Materials, EarlyView.Enhancing ultrasound transmission through an aberration layer exhibiting mismatched impedance with the surrounding medium possesses great implications in imaging and treatment. In this study, we show that a space‐coiling acoustic metamaterial with judiciously tailored structural profile can help improve impedance matching.

Brittle fracture of U-notched graphite plates under mixed mode loading
Materials & Design, 2012 Abstract Brittle fracture of isostatic polycrystalline graphite is studied experimentally, theoretically and numerically using U-notched samples under mode I and mixed mode loading (I + II) considering different combinations of the notch radius and the tilt angle of the notch.

Design of a Multistable Finger Prosthesis with Programmable Metamaterials
Advanced Engineering Materials, EarlyView.This research article shows the development of a multistable programmble metamaterial for the use as a finger prosthesis. The material was designed on different hierarchical levels where the influence of geometrical parameters and combination of mechanical elements was explored.

A Novel Approach to Estimate the Transition Temperature via Dynamic Nanoindentation
Advanced Engineering Materials, EarlyView.A new dynamic nanoindentation‐based method was developed that uses the stiffness ratio as an indicator of the elastic–plastic deformation contributions at different temperatures. The approach successfully identified transition temperatures in ferritic steel and distinguished them from continuously ductile austenitic steel.

An investigation into how the cell cycle and the Notch signalling pathway regulate pronephrogenesis in Xenopus laevis [PDF]
The connections between cell cycle exit and terminal differentiation remain poorly understood. Cyclin dependent Kinase Inhibitors (CKIs) provide a possible link between entry into the quiescent state and differentiation.

Stress Concentration Factors for Three-Point Bending Beam with Single edge U-shaped Notch
工程科学与技术, 2007 :Three-point bending beam is widely used in test of fracture properties for materials.However, a sharp crack can hardly be prepared for the specimen of quasi-brittle materials, alternatively it is reasonable to consider a U-shaped notch, then use stress
