Provided are a material testing machine that can improve the responsiveness and the stability and perform a feedback control for a test condition, and a method for controlling a material testing machine. A monitor amount conversion unit (23) calculates an estimation testing force by multiplying an elongation amount measured by an elongation amount measurement unit (22) by a control stiffness of a test piece (TP). A material test control unit (24) determines an operation amount for a servo motor (43) for reducing a deviation between an actual testing force applied to the test piece (TP) and a target testing force according to a test condition based on an estimation testing force, and executes a tensile test for the test piece (TP).

A bending apparatus for a sample is disclosed. The bending apparatus includes a translation mechanism that translates a vertical displacement/force into a horizontal displacement/force for bending. Components of the bending apparatus are fabricated from a strong, radiolucent material. In these ways, the bending apparatus is compatible with micro-CT imaging, and as such, may be used to bend a sample during imaging. In a particular application, the bending apparatus may be used to measure biomechanical properties of a bone, such as bone strength, bone material properties, fracture toughness, and fracture propagation.

Provided is a jig for a vibration test of a stator vane, for use in the vibration test for evaluating high cycle fatigue characteristics of the stator vane, and the jig is provided with a base plate that is fixed onto an excitation table of a shaker, a first fixed wall that is fixed onto the base plate in a state where a vane root end portion of a guide vane is fixed, a movable wall that is slidably placed on the base plate in a state where a vane tip portion of the guide vane is fixed, a second fixed wall that is fixed onto the base plate, and a hydraulic jack that is disposed between the movable wall and the second fixed wall, to apply a load in the span direction to the guide vane. Consequently, in the vibration test for evaluating the high cycle fatigue characteristics of the stator vane, the test simulating an actual operation state can be carried out, and an assumed deformed state can be exhibited in the stator vane to be subjected to the test.

A bending test apparatus includes a jig including first to third supporting members arranged in a first direction; a shaft member including a first shaft, a second shaft, and a third shaft extending in a second direction intersecting the first direction and respectively connected to the first to third supporting members; a driving member connected to the first shaft and providing a rotation force to the first shaft; a sliding member including a first slider and a second slider respectively connected to the second shaft and the third shaft; and a rail member extending in the first direction and guiding movements of the first slider and the second slider. When the first shaft rotates the first supporting member in a first rotation direction, the second and third supporting members rotate in a second rotation direction opposite to the first rotation direction.

The present disclosure provides a method for assessing hot coal fallout propensity of burning cigarettes based on human behavior features of ash-flicking action. The method is characterized in that the method is accomplished through an apparatus for detecting hot coal fallout propensity based on human behavior features of ash-flicking action, which include behavior features of human action of flicking cigarette ash, features of holding a cigarette, and features of force applying process and other aspects.
