THE TIME‐DOMAIN DBEM FOR RAPIDLY GROWING CRACKS
International Journal for Numerical Methods in Engineering, 1997The time-domain Dual Boundary Element Method (DBEM) is developed to analyse rapidly growing cracks in structures subjected to dynamic loads. Two-dimensional problems, where the velocity of the crack growth is constant and the path is not predefined are studied. The present method uses the dual boundary formulation, i.e.

The laplace transform DBEM for mixed-mode dynamic crack analysis
Computers & Structures, 1996A boundary element method (BEM) for the two-dimensional analysis of structures with stationary cracks subjected to dynamic loads is presented. The difficulties in modelling the structures with cracks by BEM are solved by using two different equations for coincident points on the crack surfaces.

Dynamic Modeling and Simulation of One Kind of Industry Robot by DBEM
2009 International Conference on Computational Intelligence and Software Engineering, 2009A systemic modeling method of an industry robot structure was proposed by mixed fundamental solutions, and the corresponding dynamic characteristics were analyzed. Generally, the robot structure can be modeled in beam, plate, spring and mass elements by a dynamic boundary element method (DBEM).

DBEM Analysis of Beams on Modified Elastoplastic Winkler Foundation
1991The problem of a beam on an elastoplastic Winkler medium is handled using a general Direct Boundary Element Method approach. The case of concentrated internal loading is considered, and the governing equations are obtained both following the classic beam subdivision approach and considering the beam loaded by a family of Dirac delta distributions and ...

Geomatrically Nonlinear Analysis of Cracked Stiffened Curved Panels by DBEM
Key Engineering Materials, 2008This paper presents applications where the DBEM formulations presented by Dirgantara and Aliabadi [3, 4] is combined with the multi region BEM presented recently by Baiz and Aliabadi [2], for the analysis of cracked shear deformable plates and shallow shell assemblies. Stress intensity factors are obtained using the CTOD technique. Several examples are

PREDICTING CME ARRIVAL TIME AND SPEED WITH DBEM [PDF]
, 2019 The Drag-based Model (DBM) is an analytical model that predicts the CME arrival time and speed at Earth or any other target in the solar system. It is based on the equation of motion and depends on certain initial parameters such as CME launch speed, background solar wind speed and empirically derived drag parameter.

Non-linear MSD crack growth by DBEM for a riveted aeronautic reinforcement
Advances in Engineering Software, 2009Abstract A special specimen is created cutting a rectangular notched area from the surrounding of the upper left corner of a wide body aircraft door. Then a constant amplitude fatigue traction load is applied by a special servo-hydraulic machine, in order to induce a Multi Site Damage (MSD) scenario.
