Materials Science is only part of a
complete failure analysis -- a thorough understanding of
Engineering Mechanics is also essential to performing a
thorough investigation.
What is Engineering Mechanics?
Engineering Mechanics is the branch of physics that deals
with the state of rest or motion of bodies under the action
of forces. It is one of the oldest areas of the physical
sciences, and it pervades all aspects of Mechanical
Engineering, Civil and Structural Engineering, Aerospace
Engineering, and Biomedical Engineering. Mechanics lies at
the heart of the following areas in which MME specializes:
- Solid mechanics and mechanics of materials
- Fracture mechanics
- Structural engineering
- Vibrations
- Metallurgy
- Polymer engineering and plastics
- Composite materials and structures
- Adhesion science
- Heat transfer
- Finite element analysis (FEA)
MME has several Ph.D. level engineers on staff with
professional and research experience in mechanics. The
Engineering Mechanics practice collaborates with the
Metallurgical and Materials, Laboratory Testing, Automotive,
and Non-Destructive Testing practices to complete projects
in Failure Analysis and Product Development.
Failure analysis and prevention
The ability to identify and simulate the loading history
of a part or structure and to couple this information with
the proper material behavior models is the key to
reconstructing failure events and recommending solutions.
Oftentimes, this process requires understanding advanced
topics, topics that go beyond the typical handbook
solutions.
MME is experienced in deriving solutions to
complex problems. In particular, MME engineers are trained
in advanced FEA simulations in ABAQUS, ANSYS, and NEiNASTRAN.
We routinely use FEA to solve problems involving:
- Non-linear material properties
- Large deflections
Buckling and complex failure criteria
- Contact
interactions
- Solid-fluid interactions
- Impact
- Delamination and crack growth
- Heat transfer
Product development and improvement
MME can also provide assistance in product development
and improvement. Whether you need help developing a new
product from a concept or you need assistance in improving
an existing product, MME can help. In the case of new
products, we can provide assistance in design, material
selection, material substitution, and product testing. MME
applies the same engineering concepts and techniques
employed in our failure analyses to optimize a product
design for weight, cost, or manufacturability. MME can also
provide assistance to help commercialize products in cases
where some type of performance “failure” is preventing
market introduction. Our experience includes:
- Packaging
- Consumer products
- Medical devices
- Heavy equipment
- Construction
- Military
