Threaded Bolted Joint Modeling Mimics Reality with Inputs from Experimental Data

Understanding the threaded bolted joint model is critical to produce accurate and meaningful simulation results for the behavior of these common fasteners under actual operating conditions. Knowing what the results should be, through measurement (physical or gauged), is half the battle. The second half of this battle is, of course, creating a model that will support these results.

This webinar will have two parts:
Part One will discuss the physical science behind what happens when a threaded fastener has torque applied to it and clamp load is developed. The science behind this is in the form of experimental data obtained from a fastener test laboratory using both strain-gauge and ultrasonic technology. The data presented will be applied to total torque, thread torque, under-head torque, developed clamp load, and thread and under-head coefficients of friction. This set of data primarily describes the act of torquing a threaded fastener.
Part Two will simply apply the data generated in the lab to a full 3-D, rotating threaded fastener FE model.
