1. How to Ensure Product Performance and Reliability with
Finite Element Analysis?

Finite Element Analysis (FEA) is a technique normally conducted by software to produce models of
materials or designs that can then be subjected to virtual stresses. Hence; FEA engineers utilize FEA
analysis services to envisage material and product performance under a range of operating conditions,
thereby providing real cost benefits over manufacturing and testing prototypes and providing
captivating insights into the behavior of the product in this case; we are taking the product as a seal. But
the problem is that the model is run with the help of intricate algorithms in a theoretical and unrealistic
world where real world testing, expertise and human input is required to bring into life and significantly
augment the consistency of the results. Picture-perfect results are not always generated.
A company has industrialized its FEA software using finite element analysis services to provide
consistent seal-related modeling on a per application basis. This includes a clear, precise and all-inclusive
plan of boundary conditions to be created, by taking into account hardware interaction with the product
or whether the seal needs to be stretched or twisted for installation. They have integrated a library of
precisely modeled materials, both metallic and non-metallic which is needed to provide results that are
as close to real-world scenario as possible.
The company performs bulk of its analysis on non-metallic materials which necessitates non-linear
modeling. This depends profoundly on the quality of material properties utilized in the model.
Consequently all materials need to be comprehensively tested in the real world to determine stress-

2. strain curves, Poisson ratios and all other physical material properties. The precise modeling of the seal
before parameters like stresses are used which is principal for a successful analysis.
Once a comprehensive model of the seal has been industrialized, an all-inclusive understanding of the
forces and stresses that the product or seal will be subjected to is required. An assortment of
operational conditions can be premeditated, for example; a flat or varying temperature and pressure
conditions or dynamic movement of the hardware surrounding the seal. Calculating for the countless
possibilities can be intricate and should be done on a case-by-case basis, needing human analysis and
knowledgeable operators.
Whether a 2D or 3D model is selected depends on the application. 2D models are for axi-symmetrical,
plan strain and plane stress analysis, which helps in validating how a product will install, grow from
thermal expansion and react to forces or pressures applied. Whereas a 3D model offers a more
comprehensive picture of a product such as a seal that operates under intricate and often varying
stresses, consenting for non-uniform profiles or voids. 3D analysis is required to envisage more intricate
profiles enhancing the reliability of the results obtained and for simulating unconventional positions or
loads for axi-symmetrical geometries.
How can FEA Help in ensuring product performance and reliability?
FEA services can be extremely useful in ensuring maximum product performance; in this example
guaranteeing maximum seal life in an application. It also helps in envisaging seal deformation under
load, the sealing contact forces or the contact pressure distribution, the latter is particularly valuable for
augmenting dynamic seals or to reverse engineer prevailing problems to discover the root causes. This
helps in predicting reliability of a product.
