When it comes to aircraft and spacecraft structural
analysis, AMPS boasts a highly competent and qualified staff with
experience in a wide variety of structures and analysis.
Linear Static Analysis
AMPS has broad experience in linear analysis of complex
aerospace structures, for both loads and detailed stress analysis. This
includes classical and finite element determination of strength,
stiffness and stability. Linear
analysis techniques address quasi-static loading, thermal stresses and
distortion, and hygroscopic stress and distortion analysis. AMPS
associates have worked with a wide variety of metallic and non-metallic
aircraft and spacecraft structures.
- Loads and Detail Stress
- Finite Element Modeling
for Strength, Stiffness, and Stability.
- Metallic and
Non-linear Static Analysis
AMPS associates have experience in sophisticated
non-linear analysis methods. This includes the incorporation of
plasticity, time dependency, contact solutions, and large displacement
finite element analysis. A number of the AMPS associates have extensive
experience of non-linear stability solutions and post-buckling
- Plasticity, Time
Dependency, Contact Solutions, and Large Displacement FEM.
- Non-linear Stability
Solutions and Post-buckling Analysis.
AMPS associates have experience with military and civil
aircraft fatigue analysis including mission profile fatigue and high
cycle fatigue associated with rotating engine components. This includes
the development of load spectra, fatigue crack growth analysis, and
sizing of fatigue critical structures. AMPS personnel have also
addressed low cycle fatigue issues associated with plastic deformation
- Military &
- Mission Profile Fatigue
and High Cycle Fatigue (Rotating Engine Components).
- Load Spectra
Development, Fatigue Crack Growth Analysis.
- Low Cycle Fatigue
Issues Associated With Plastic Deformation and Creep.
AMPS personnel have extensive expertise various types of
dynamic analysis. Using finite element analysis techniques, we can
address a variety of dynamic issues including normal modes, modal
frequency response, random vibration, structural acoustic response,
shock, flutter, linear, non-linear, and transient dynamic problems.
- Normal Modes, Modal
Frequency Response, Random Vibration, Structural Acoustic
- Shock, Flutter, Linear,
Non-linear, and Transient Dynamic Problems.
AMPS personnel have experience with a variety of
non-metallic and composite hardware. This ranges from to laminated
carbon fiber/epoxy matrix structures to short fiber composite parts
certified to FAA and JAA requirements, refractory composite structures
used for hypersonic and reentry vehicles, and PMR15 composites for jet
engine applications. AMPS, Inc. has developed its own laminate codes,
which addresses in plane and through the thickness stresses and
properties as well as edge effects.
