Identification of Lap Joint Dynamics Using Interfacial Nanocomposite Force Sensor

Machine tools are complex structures consisting of several parts connected through different types of joints. Mechanical joints affect dynamics of the machine tools significantly, and any virtual model of the structure should include joint properties. It is desirable to use an interfacial sensor ins...
