Mounting jig assemblies for supporting test components on testing platforms of testing assemblies
The mounting jig assembly includes a jig body and a clamp assembly. The jig body includes a top surface, a bottom surface, a front wall, a rear wall, and a pair of side walls. The jig body is configured to support the test component on the testing assembly with the test component in contact with the top surface and the bottom surface in contact with the testing platform. The jig body defines an elongated opening that extends between the top surface and the bottom surface. The top surface being oriented obliquely with respect to the bottom surface. The clamp assembly is moveable between a clamped position and an unclamped position. In the clamped position the clamp assembly inhibits movement of the test component with respect to the jig body. In the unclamped position the clamp assembly permits movement of the test component with respect to the jig body.

ANALYSIS OF MATERIAL PROPERTIES OF INTERNAL SURFACES USING MACHINING PROCESSES TO ENABLE STRESS RELIEF IN THE MATERIAL UNDER TEST
Analysis of residual stress in materials is often done in static conditions in a laboratory. Accurate systems and methods for performing these analyses in a dynamic, non-laboratory environment are notoriously difficult and can be very inaccurate. A method using a portable, field deployable apparatus having greater accuracy than currently available is disclosed whereby accurate and repeatable residual stress analysis may be implemented in non-laboratory environments leading to greatly improved diagnostics, maintenance and life limit prediction. Especially the analysis of a pipe or channel can be facilitated with this invention.

Method of designing and optimizing fixed cutter drill bits using dynamic cutter velocity, displacement, forces and work
A method includes simulating a cutting tool drilling an earth formation by incrementally rotating the cutting tool at a plurality of time intervals, determining a true trajectory of a cutting element disposed on the cutting tool for the duration of the plurality of time intervals, and determining a dynamic work profile for the cutting element based on the true trajectory and a force acting on the cutting element at each time interval.

Wear determination for agricultural implement
An agricultural implement includes an electrically conducive ground engagement tool with an opening and a sensor having a first and second conductor. An insulative material extends around a periphery of the opening to a contact area, and a conductive material fills the opening and extends to the contact area to electrically couple the conductive material to the ground engagement tool. The first conductor electrically couples to the conductive material, and the second conductor electrically couples to the ground engagement tool. A controller may receive a signal from the sensor indicative of an electrical resistance between the first and second conductors, determine the ground engagement tool has worn past a threshold amount in response to receiving the sensor signal indicative of the electrical resistance being above a threshold value, and output an output signal in response to determining the ground engagement tool has worn past the threshold amount.
Method For Determining The Wear State
This invention relates to a method for determining a wear state of a chisel, a chisel holder, and/or a chisel holder replacement system equipped with a chisel and chisel holder. For this method to give the user qualitative and quantitative information about the wear, according to one embodiment of this invention, a position of at least one point of the chisel and/or the chisel holder is determined by a contactless measurement method and a corresponding measurement result is compared in a switching unit to a reference value stored in a memory device.

DEVICE FOR TEAR ANALYSIS OF FILMS
A system and method for performing a tear test are described herein. The system may include a fixed clamping station configured to hold a first portion of a film specimen and a movable clamp coupled to an actuator, the movable clamp may be configured to hold a second portion of the film specimen. The movable clamp may be configured to move in a direction away from the fixed clamping station to tear the film specimen. The system may include a slitter blade configured to cut the film specimen at a location between the fixed clamping station and the movable clamp. The system may include a load cell coupled to one of the fixed clamping station and the movable clamp. The load cell may be configured to measure a force associated with tearing of the film specimen. The actuator may be configured to manipulate the movable clamp along a trajectory.
