Investigating the Dynamic Behavior of Gabbro Specimens With Echelon Joints
Investigating the dynamic behavior of rock specimens with echelon joints based on SHPB tests. ABSTRACT To reveal the influence of dynamic load on the dynamic damage behavior of jointed rock masses, split Hopkinson pressure bar (SHPB) system was employed to test platy gabbro samples with joint angles of 15°, 30°, 45°, 65°, and 75° at an impact pressure ...

Direct‐Write Printing of Multicolor Electroluminescent Films for Stretchable Display
This work presents a mask‐free, fully printable alternating‐current electroluminescent (PACE) film using a direct‐write printing strategy. The multicolor PACE film, available in blue, green, and orange, reaches a thickness of ≈150 µm and achieves 180 cd m⁻2 at 6 V µm⁻¹.

The research of hourglass worm dynamic balancing simulation based on SolidWorks motion
Hourglass worm is extensively used in industry due to its characteristic of heavy-load and a large reduction ratio. Varying sizes of unbalanced mass distribution appeared in the design of a single head worm.

Displacement of the worm axis relative to the wheel axis under load is considered to be the helical movement rotating about the instantaneous axis. In order to avoid the influence of the displacement of gear axes under load upon tooth contact, the authors propose that the surface normals should be intersected perpendicular to the direction of helical ...
