Finite element analysis involves breaking down geometric models into small components through meshing for use in structural analysis.
Why do we need to generate complex finite element models for structural analysis?
While there are various reasons for creating a mesh in finite element analysis, this content will primarily focus on summarizing it into three key points.
1) Discretization of Physical Systems :
Most structures or systems have complex and diverse shapes.
To handle this complexity, finite element analysis requires breaking down these structures into smaller elements through meshing, allowing for the discretization of the physical system.
By discretizing the physical system into smaller elements, we can establish mathematical models for each element.
2) Approximation of Small Displacements :
Real-world structures often require analysis of their response to small displacements under complex loading and boundary conditions.
By approximating these small displacements, it becomes possible to construct mathematical models describing the relationship between forces and displacements.
3) Analysis and Optimization :
Modeling through meshing in finite element analysis enables the prediction of stress, deformation, and various physical properties of structures or systems.
This facilitates predicting aspects such as structural integrity, strength, deformation, and, if necessary, performing optimization or design changes.
Finite element analysis inherently involves approximating complex physical systems into manageable mathematical models.
By generating a mesh, we can analyze and optimize the behavior of structures or systems.
Therefore, engineers need to approach mesh generation with careful consideration and thoughtful planning.
