APPARATUS AND METHOD FOR ATTACHING A LOAD INDICATING DEVICE TO A FASTENER

摘要

A method and apparatus for attaching a load-indicating device to a fastener so that the accuracy of the load-indicating device is not affected by yielding and non-uniform elastic deformation of the fastener. The apparatus is attached to the fastener in a region of the fastener which is not likely to yield or elastic deform in a non-uniform manner when the fastener is loaded. The region may be determined using finite element analysis, physical experimentation or other means such as by mathematical computation. By securing the loadindicating device in such a manner, the device is not affected by yielding or non-uniform deformation of the fastener, cyclic loading, shock or thermal expansion.
