摘要： This document describes systems and methods for integrated mechanical loading of tissue. The system includes a three-dimensional tissue comprising organic material. The system includes a strip of bendable material. The strip includes a first region proximate to a first end of the strip coupled to the tissue. The strip includes a second region near a second end of the strip for coupled to the tissue, the second end being opposite the first end, wherein the tissue exerts a force on the strip to bend the strip, the force caused by contraction of the tissue, and wherein the strip exerts a stress on the tissue.

摘要： A method includes forming, by a laser beam supplied by a laser cutting system, a laser-cut line in each of a plurality of glass samples. Each different laser-cut line in each different glass sample of the plurality of glass samples is formed when the laser cutting system is at a different process setting. The method also includes subjecting each of the plurality of glass samples with the laser-cut lines to a break test, and obtaining a plurality of break strength values. Each different break strength value of the plurality of break strength values is indicative of a laser-cut line quality of the respective glass sample of the plurality of glass samples.

摘要： The present application provides a testing device. The testing device includes: a box, a pressing mechanism, a sliding mechanism, a transmission mechanism, and first clamping mechanisms. The pressing mechanism is located inside the box. A gap between the pressing mechanism and the first side of the box is used to place substrates to be tested. The pressing mechanism is slidably connected to the sliding mechanism. The transmission mechanism is connected to the pressing mechanism to drive the pressing mechanism to move. Each first clamping mechanism is used to hold one of the substrates to be tested.

摘要： A racquet including a frame including a head portion, a handle portion, and a throat portion. The head portion forms a hoop that defines a string bed plane. The head portion of the racquet being formed of a fiber composite material. When the racquet is tested under a racquet forward/rearward bending test, the racquet has a forward/rearward deflection with respect to the longitudinal axis of at least 8.5 mm when measured in a direction that is perpendicular to the string bed plane and perpendicular to the longitudinal axis. When the racquet is tested under a racquet torsional stability test, the racquet has an angular deflection of less than 5.5 degrees about a longitudinal axis.

摘要： Disclosed is a test rig and a method for mechanical load testing of a specimen extending along a longitudinal axis from a first specimen end to a second specimen end and comprising a composite material extending along the longitudinal axis from a first composite end to a second composite end and a primary elongate component extending along the longitudinal axis from a first primary component end to a second primary component end, the first primary component end being the first specimen end, and wherein the composite material encapsulates the primary elongate component along a first interface region extending along the longitudinal axis from the second primary component end to the first composite end. The method comprises applying a load to the specimen resulting in an axial load component and a bending moment being imposed to the specimen.
