We Solve Component Life
VEXTEC's core technology is engineering design and simulation.
We provide predictive models and computer aided engineering
services in the areas of product reliability, risk assessment
and life prediction. The models are used to simulate fatigue,
corrosion and other damage mechanisms in structural, mechanical
and electronic products. We have helped clients in a variety of
industries make their components last longer, while reducing
warranty costs, maintenance costs and capital expenditures. If
you are interested in accelerating product development,
improving manufacturing consistency, modifying a product to meet
a more severe service condition, or solving a difficult lifing
issue, VEXTEC can help.
What makes us different from other consulting companies is our
proprietary software, which we have been developing since
VEXTEC's founding in 2000. We have received over $25 million
from the United States Department of Defense through its
Innovative Research programs to develop this technology. During
this time VEXTEC has been granted seven Patents & was recognized
in 2009 by Forbes magazine as "America's
Most Promising Company".
VEXTEC's Lifing Software
is Based on Two Basic Principles
We call our software Virtual Life Management ® or VLM
® which is based on two basic principles:
are not homogeneous on the microstructural level, which is
the level on which cracks initiate and usually spend the
majority of their life.
are much faster and cheaper than physical testing.
VEXTEC uses probabilistic models which simulate the actual
failure processes. Cloud computing allows us to run the
simulations much faster. Once the model is set up and calibrated
with test data, it can be used to evaluate the effect on life of
potential changes to a component's design, material, and
processing. Since this is done with a computer model instead of
additional testing, these models can be used in a variety of
industries for various purposes (component re-design, prediction
of fleet failures, prognostic health management, etc.) on many

We provide consulting services to improve product reliability.
VEXTEC offers a variety of services to suit your needs from
product design to failure analysis. Using VLM, we simulate
fatigue life and corrosion damage in structural, mechanical and
electronic products. The VLM models VEXTEC develops in an
initial engagement are available for continuous use throughout
the product lifecycle, saving time and money from design to

Industries We Serve
VEXTEC's lifing approach is used in a variety of industries such
as industrial equipment, manufacturing, medical devices,
aerospace and automotive. It can be used for various purposes
throughout the product life-cycle, including component redesign,
prediction of fleet failures, prognostic health management, and
in-service applications. Our methods have been used to address
mechanical fatigue, friction and fretting wear, coatings,
corrosion, and other damage mechanisms. VEXTEC has analyzed a
wide variety of materials, including steels, aluminum, titanium,
nickel, composites, solder (leaded and lead-free), plus
directionally-solidified and single crystal materials.
Reduce physical testing requirements and prototyping and
accelerate development, and bring new/improved products to
market more quickly and economically.
Reduce unexpected equipment downtime, improve productivity,
align vendor specifications with reliability, and lower
manufacturing costs and annual capital expenditures.
Resolve application and performance issues, quantify the
impact of changes in operating conditions, and determine
design and material processing criteria for new applications
before placing products into service.

“VEXTEC’s modeling showed that a bearing re-design would not
solve the APU problem, but a change in lubricant would."
used VEXTEC's VLM approach to get a repair method certified
by the Federal Aviation Administration (FAA). Using VLM
resulted in a 50% reduction in physical testing
requirements, and 70% reduction in preparation time for
certification application. According to EB Airfoils
president, James Bickel
"This will get us to market more quickly, and that's a big
was looking to determine the fatigue reliability of medical
implant airway stents with material from two different
vendors. Using VLM they were quickly able to determine the
lifetime at which 1 out of 1000 stents would fail for the
two different materials, and select the appropriate material
based on simulated durability instead of basing their
decision solely on testing to determine the average lifetime
of limited number of stents.
"This study was able to demonstrate VLM’s ability to iterate
with material substitution, vendor management, sensitivity
analysis, design trade studies and design optimization."
ran numerous gears through a demanding test cycle. According
to gear industry design standards, there should have been no
failures before 10,000,000 cycles, VEXTEC's modeling showed
4% failures, which was very close to the actual test failure
