RSIME Finite Element Modeling

Two finite element programs are used by RSI Materials Engineering:

LS-DYNA  An extremely powerful non-linear explicit finite element program that can model most all phyically occuring problems.  It is often used to model material deformation, impacts, vehicle crashworthiness, sheet metal stamping, etc...  More...

COSMOS  When less complex problems are addressed, COSMOS is the FEA program of choice.  It is very quick and is paired with Solidworks, a 3-D CAD program.  This allows for analysis and revisions to be done very efficiently.  COSMOS focuses on the following:

What is finite element modeling?
Finite element analysis (FEA) is a computational modeling method that discretizes a complicated component geometry into simple, manageable "finite elements".  this allows for easy calulation of stresses and strains.

Why would I want to use FEA?
Finite element analysis allows for many different designs under varying load scenarios to be tested without the time and expense of full scalse physical testing.  Costs and development time can can be decreased with finite element analysis.  FEA can also be used as a failure analysis tool to help determine the root cause of a failure.  Finite element models are also helpful with litigation due to their descriptive and easyly understood plots of stresses.

Why should I use RSI Materials Engineering for my modeling needs?
Not only is RSIME a professional and experienced finite element modeling firm; we are also a fully equipped materials testing laboroatory.  We have the capability to physically and computationally test your component to give you the complete analysis you need.
