Tapered, arched beam stiff mass matrices ?

Click For Summary
SUMMARY

The discussion focuses on the derivation of stiffness and mass matrices for tapered and arched beam elements in 3D frame structures with six degrees of freedom (6DOF) per node. The user seeks specific methodologies and resources, as general searches yield insufficient information. A recommendation is made to use the term "curved" instead of "arched" for more effective results, particularly in the context of tapered curved beam element formulation.

PREREQUISITES
  • Understanding of 3D frame element analysis
  • Familiarity with stiffness and mass matrix concepts
  • Knowledge of degrees of freedom (DOF) in structural mechanics
  • Experience with finite element method (FEM) applications
NEXT STEPS
  • Research "tapered curved beam element formulation" for relevant methodologies
  • Explore finite element analysis software that supports 3D frame elements
  • Study the derivation of stiffness and mass matrices in structural mechanics
  • Investigate existing literature on 6DOF modeling in beam elements
USEFUL FOR

Structural engineers, researchers in computational mechanics, and students studying advanced topics in finite element analysis will benefit from this discussion.

Hi all,

Actually I'm supposed to run and find results in google search. But that doesn't give any useful information, retrieves some nomenclatures which deals with estimation of technique or deriving the stiffnesss mass matrices for 2D frame element. But I'm looking for 3D frame element with 6DOF per node.

The title may seem a bit confusing, I'm looking the stiff and mass matrices for tapered beam, arched-tapered beam and arched beams.

Does anybody can give any entry-point on that ?

Regards,
