FEA
FEA stands for this.
Finite Element analysis
This feature removes material from a part.
What is an extruded cut?
Permanent deformation due to excessive stress is called this.
What is yielding?
This is the internal force per unit area within a material.
What is stress?
The first step in machine design where requirements are identified.
What is problem definition?
This divides a model into small elements for analysis.
What is meshing?
This tool creates symmetrical geometry about a plane.
What is mirror?
Sudden fracture without significant deformation is known as this.
What is brittle failure?
The ratio of stress to strain in the elastic region.
What is Young’s Modulus?
This factor accounts for uncertainties in loading and material properties.
What is factor of safety?
These must be applied before running a simulation to prevent rigid body motion.
What are boundary conditions?
These views show internal features of a component.
What are section views?
This failure theory is commonly used for ductile materials.
What is the von Mises criterion?
This bending stress formula is written as σ = My/I.
What is the flexure formula?
This design approach ensures stresses remain below yield strength.
What is static design?
This plot shows stress distribution using color gradients.
What is a stress contour plot?
This drawing element shows size and tolerance information.
What are dimensions?
This failure occurs after repeated cyclic stresses below yield strength.
What is fatigue?
When a material returns to its original shape after load removal, it is in this region.
What is the elastic region?
This iterative method improves design by evaluating and refining concepts.
What is the design iteration process?
Convergence ensures this important simulation quality.
What is mesh independence (solution accuracy)?
This file format is commonly used for manufacturing CNC parts.
What is a STEP file?
This phenomenon occurs at high temperature under constant stress over time.
What is creep?
he shear stress in a circular shaft is given by τ = Tr/J.
What is the torsion formula?
This diagram helps select materials based on performance indices.
What is an Ashby chart?
