Physical Testing |
 |
HLA has extensive experience in
designing and conducting the physical testing of structures. |
|
CAD Design
|
|
We have in-house personnel
with many years of experience in designing and drafting.
We can create engineering
drawings and detailed fabrication drawings. |
|
Fatigue Program
|
|
We have developed our own Fatigue
Program, using either the Strain Life or Modified Goodman approach.
We can cue directional, principal or signed Von-mises stress
components. |
|
Damage Tolerance
|
|
The Science of Damage Tolerance is a
multidisciplinary subject, involving a combination of fatigue and
fracture of metallic and polymeric materials. |
|
Stress Analysis |
|
We have many years in performing
stress analysis to exacting requirements; classical & FEA; formal
reports & documentation; all materials: aluminum, carbon &
stainless steels, composites and Elastomers. |
|
Finite Element Analysis |
|
We have over 90 years combined
experience, and are expert at Finite Element Analysis - both
Linear and Non-linear. |
|
Consulting |
|
As a full service Structural /
Mechanical Engineering Company, we can provide both Turn-Key and
Special Project Design and Computer/Stress Analysis to companies
locally, nationally and internationally: Trinity Industries,
Goodyear, General Electric, Hughes Simulation, Raytheon, Shell
Oil, Andrew Corporation, to name a few. |
|
Transportation |
|

and cryogenic tank cars |
|
Industrial |
|
Cranes and
Craneways, Heavy Industrial Equipment, Mining Equipment, Industrial
Buildings, Failure Analysis |
|
Power |
|

Catalytic Reduction Systems, Wind Energy Generation |
|
Elastomers |
|
HLA Engineers, Inc. has had a long
history performing analyses of difficult problems using elastomers.
|
|
Belt Model |
|
A full belt with a steel cable embedded
in rubber. |
|
Bridge Pavement Seal |
|
A bridge pavement seal that would
provide a sealing force within a specification tolerance and a
specification deflection. |
|
Laminated Flex Joint |
|
Laminated Flex Joints are used as the
joints in the tension legs of drilling platforms and other
applications in the oil industry where low moments and no slip-stick
friction are desired. |
|
Seal Evaluation |
|
The objective of this analysis was to
evaluate a seal to determine why is was leaking and then redesign to
prevent the leaking. |
|
Valve Diaphragm |
|
This axi-symmetric model consists of a
Plug Bottom which is bolted to the Plug Top, thereby compressing the
two o-rings and the diaphragm with the two rigid contact surfaces. |
|
Annular Packer |
|
An annular packer is used in the oil
industry to shut off a well. |
|
Gas Spring |
|
The deformation changes the volume
available for the gas, therefore the gas pressure changes. |
|
Rubber Curing |
|
The objective of the analysis is to
determine what initial conditions and what cure conditions will be
needed to produce a fully cured part. |
|
Shaft Sealing |
|
The model is a seal between two
concentric shafts. The material model for this axi-symmetric model
is a two coefficient Mooney-Rivlin. |
|
Auto Gear Shift Boot |
|
The objective of the analysis was to
design a boot for an automotive console gear shift that would
provide a uniform moment when shifting. |
|
Intravenous Flow Stopper |
|
This device is intended for use in
hospitals to shut off the flow of intravenous solutions to the
patient. |
|
O Ring |
|
This is a simple axisymmetric model with
an o-ring modeled in a gland with a simulated shaft. |
|
Sports Bottle Cap |
|
The objective of this project was to
design an elastomer cap for a sports bottle which will stay closed
automatically and will only open up when the user wants it to and
not when a transient pressure is applied. |
|
Railcar
|
|
HLA Engineers, Inc., has worked on
railcar design and analysis since the beginnings of the company in
1974. |
|

|
Petro
|
|
HLA Engineers, Inc., has a long history
of activity in all types of petro-chemical projects. |
|
Composites
|
|
The Design and Analysis of Structural
Composites requires the use of micro-mechanics and macro-mechanics
concepts. |
|
Cargo
|
|
