FEA (Finite Element Analysis)
Finite element analysis (FEA) is the use of calculations, models and simulations to predict and understand how an
object might behave under various physical conditions. Engineers use FEA to find vulnerabilities in their design
FEA uses the finite element method (FEM), a numerical technique that cuts a structural object into many pieces, or
elements, and then reconnects the elements at points called nodes. The FEM creates a set of algebraic equations
which engineers, developers and other designers can use to perform finite element analysis.
Using finite element analysis can reduce the number of physical prototypes created and experiments performed
while also optimizing all components during the design phase.
The slide show below shows the FEA results from subjecting mechanical and structural components to loads.
Tent Support Structure Stress, Load = 100 mph (161km/hr) Wind.
Chain Hook Stress, Load = 5 kips (22.2 kN).
IPV Stress, External Pressure = 1000 psi (6.9 MPa).
Armored Cable Termination Stress, Load = 10 kips (44.5 kN).
Boat Lift Piling Support Stress, Load = 3 kips (13.3 kN).
BLAT Drive Pipe Stress, Load = 2000 kips (8.9 MN).
BLAT Top Breech Lock Stress, Load = 2000 kips (8.9 MN) .

What FEA Can Do For You
FEA can be used to calculate
stress and deflection in machine
parts, assemblies, weldments,
and sheet metal parts that have
geometries that don't allow the
use of classical stress analyis
SolidWorks Simulation improves
product reliability by optimizing
parts and assemblies for many
environments and scenarios. It is
a cost effective way to predict a
product's real world physical
behavior by virtually testing
