Simulation has become indispensable for innovative design and problem-solving in the ever-evolving engineering field. Amidst thе array of computational tools availablе for such simulations, Finitе Elеmеnt Analysis (FEA) stands as a cornеrstonе tеchniquе, offеring unparallеlеd prеcision and vеrsatility.
FEA is a numеrical mеthod that prеdicts how a product reacts to real-world forces, vibration, hеat, fluid flow, and other physical еffеcts. It is particularly significant in mеchanical simulations, allowing engineers to test dеsigns against various parameters and optimize thеm without nееding physical prototypes.
This article focuses on ANSYS Mеchanical, a leading software in the FEA domain that harnesses thе роwеr оf FEA for virtual tеsting and analysis of mеchanical componеnts and systеms. It offers a dynamic еnvironmеnt with a complеtе rangе of analysis tools, from prеparing gеomеtry for analysis to connеcting additional physics for even greater fidelity.
ANSYS, Inc. is an American multinational company that develops and markets CAE/multiphysics engineering simulation software for product design, testing, and operation. It offers its products and services to customers worldwide. It helps engineers design complex, highly nonlinear, and large models and is used to simulate computer models of structures, electronics, or machine components for analyzing strength, elasticity, and temperature.
ANSYS software offers a wide range of features and benefits:
Fast Simulations: ANSYS software includes multiple solver technologies that run in parallel and scale efficiently up to 1000+ cores. GPU technology can also be leveraged for additional parallel computing power.
Linear Dynamics: Modal, harmonic response, random vibration, and spectrum response (seismic or shock) can be solved with ANSYS Mechanical.
Acoustics: ANSYS software conducts acoustic simulations to better understand systems’ vibroacoustic behavior.
Nonlinearities: Users can simulate the behavior of elastic materials as they undergo plastic or hyperelastic deformation materials like metals and rubber. Nonlinear simulation within ANSYS Mechanical design also considers contact and large deflection of moving parts relative to each other, with or without friction.
Short Fiber Reinforced Composites Workflow: ANSYS software enables engineers to accurately and easily simulate plastic parts made through injection molding. The injection process data, including fiber orientation and density details, are imported and mapped seamlessly onto a finite element mesh in Mechanical and complemented with accurate material behavior at each element.
Back to CAD Workflow: This new workflow allows users to turn their topology optimization results into computer-aided design (CAD) geometry. The “autoskin” feature saves the user time otherwise spent on recreating geometry.
Finite Element Analysis (FEA) is a numerical method for predicting how a product or a structure will react to physical forces, such as vibration, heat, fluid flow, etc. It uses the finite element method (FEM), which divides the region of interest into smaller parts called finite elements. The method also applies a chosen approximation over each element to determine its behavior.
Three governing equations form the basis for finite element analysis:
Equilibrium Equations
Strain-Displacement Relations
Constitutive Equations (Hooke’s Law)
FEA is important because it allows engineers to simulate a design without building a physical model. Using finite elements allows for modeling multiple material types, testing complicated geometry, and recording local effects acting on a limited design area.
Applications of FEA include:
Simulating physical phenomena and reducing the need for physical prototypes
Optimizing components as part of the design process of a project
Anticipating potential design flaws and lowering the risk to the product
Testing the influence of various situations on the design (stress, vibration, buckling, fatigue, creep, heat, and so on)
Estimating structural behavior and strength, design optimization, modeling, and simulation in various engineering disciplines
Piping design where rigidity is a governing factor
ANSYS uses FEA solvers to customize and automate solutions for structural mechanics problems and analyze multiple design scenarios. ANSYS Mechanical is a dynamic tool with a complete range of analysis capabilities, from preparing geometry for analysis to connecting additional physics for even greater fidelity.
ANSYS offers several benefits when used for FEA, including:
Imports various geometric shapes from different CAD software and use them to perform simulations.
Removes the need for a physical prototype, which can be tested for adverse circumstances.
Tests the product’s behavior in response to different inputs.
By reducing costs and the time taken to produce their products, ANSYS software ensures the efficiency of a company in this competitive world.
