Bolt Preload Effect on Fatigue Life Preloaded bolts and rods are present in a very wide range of engineering design solutions and geometries where the effects of high cyclic loading are critical. These include, but are not limited to, high-speed railway…

Two Interesting Examples of Mesh Gluing The mesh glue feature in ADINA is a practical and powerful technique suitable for many types of analyses. It was introduced in ADINA 8.3 and has been extensively used. The feature was already described in a previous…

A "Twist" in the Buckling of Beams Three-dimensional beam models are widely used to represent structural behaviors. Bridges, buildings, rotor blades, components of motorcars, and many other slender structures can frequently be modeled, in the first…

The 3D-bolt in ADINA In the constructions of many structures, bolts are used to hold structural parts together, and there can be many bolts in a model of a structure. It is important to be able to model the bolts and their interactions with the parts…

Advanced Structural Modeling with ADINA’s Connector Element Introduction It is often desirable to replace complex or expensive solid element models with structural elements possessing equivalent mechanical responses. Beam, truss, and spring elements…
