Acoustic Properties of Wood [PDF]

The Journal of the Acoustical Society of America, 1969
A square redwood plate was progressively cut, removing crossgrain and longitudinal-grain strips, with simultaneous acoustic measurements made of strips (beams) and plate. Findings show that regions near the ends of a free beam or plate do not contribute to losses.

Laser Powder Bed Fusion of Alumina: Effects of Scanning Strategies on External and Internal Defects

Advanced Engineering Materials, EarlyView.
This study investigates how scanning strategies affect pure alumina in laser powder bed fusion. Linear 45° scanning yields uniform surfaces but high porosity, while the island‐concentric strategy provides higher density with through‐holes favorable for infiltration. Findings highlight pathways toward optimizing defect‐free alumina parts.
