Simulation of Broken Dam The animation above is a simulation of the flow of water when a dam is broken. The simulation demonstrates the use of the VOF method available in ADINA. The VOF method is a surface-capturing method for solving flows possessing…

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…

Study of Bearing Stiffness of Drilled Shafts Socketed in Heterogeneous Rock The rock-socketed drilled-shaft system is widely used to support heavy structures such as high-rise buildings and bridges. New construction design practices, such as the Load…

Stability Analysis of Overlapping Tunnels during Shield Tunneling Shield tunneling using a large tunnel boring machine (TBM) is widely used to construct underground tunnels for subways. During tunneling, the soil strata substance is pressed, crushed…

Stage 1: 4-meter lateral sliding, Stage 2: 5-degree rotational sliding Large Frictional Sliding Analysis of a Prestressed Concrete Bridge Girder Nowadays, aging infrastructure in the developed world has increased the need for in-depth analyses of…

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…

Simulation of Buckling of Bridge Braces - T he San Francisco-Oakland Bay Bridge The California Department of Transportation (Caltrans) initiated the California Toll Bridge Seismic Retrofit Program to determine the vulnerability of California's major…

Seismic Evaluation of the Cooper River Bridge (by SC Solutions, Inc., California) The design of the new Cooper River cable-stayed bridge in Charleston, South Carolina, was analysed by SC Solutions, California, using ADINA. The structure has a main span…

Seismic Isolation of the Aurora Bridge In modern earthquake engineering, design for seismic isolation has become increasingly important for the prevention of devastating damage in a major earthquake. One effective and practical method for seismic isolation…

Modeling Concrete in ADINA Concrete is a very important material and present all around us, in concrete bridges, dams, buildings, and so on. Hence it is important to be able to model a concrete material adequately in finite element analyses. However…

Small deformation Large deformation Moment-curvature Relation for a Beam Using Shell Finite Element Model In many practical applications it is advantageous to use a hierarchical modeling approach. In general, it involves using a higher…

Dam Safety in an Earthquake An earthquake can cause a dam to crack or dislocate, or even cause its component blocks to detach. The damage can result in uncontrolled water release or a catastrophic flood. Numerical methods such as finite element analysis…
