Stress relief at corner joint and effect of stress relief on fatigue strength.

QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 1986
Some series of large-scale fatigue tests have already been conducted on the longitudinal groove weld, which is familiar at the corner welded joint of box sectional members. It was cleared in these tests that the fatigue crack originated from the root blowhole and that the fatigue strength was considerably lower because of the effect of the tensile ...

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

Advanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

The first composite increment: Dependency on placement technique for interaction behavior with maturing dentin-adhesive bond at pulpal floors in deep occlusal cavities – A comprehensive review

Saudi Journal of Oral Sciences
Introduction: When the traditional incremental technique is used for direct placement of composite resin in a deep occlusal cavity, each increment (2 mm or thicker) is individually cured where it undergoes hardening and shrinkage.

Micropatterned Biphasic Printed Electrodes for High‐Fidelity on‐Skin Bioelectronics

Advanced Functional Materials, EarlyView.
Micropatterned biphasic printed electrodes achieve unprecedented skin conformity and low impedance by combining liquid‐metal droplets with microstructured 3D lattices. This scalable approach enables high‐fidelity detection of ECG, EMG, and EEG signals, including alpha rhythms from the forehead, with long‐term comfort and stability.
