Although there is collaboration and development of multidisciplinary activities which require professionals with different technical background, LAMEF is divided in working groups with their own laboratorial infrastructure and researchers.



The Failure Analysis Group works proposing actions to avoid or mitigate catastrophic failures and also indicates changes to be made in the product or process in order to optimize performance of engineering components in general. Besides failure analysis, GAF additionally carries out metallurgical characterization of ferrous and non-ferrous materials with total or superficial heat treatment among other metallurgical conditions.

Several equipment are routinely used to carry out the various activities in the Failure Analysis Group, such as low magnification and optical microscopies, optical emission spectrometers, hardness testers, scanning electron microscopies etc.


The Mechanical Testing Group has started its activities in the 1990s.

With a complete laboratorial infrastructure and a highly qualified and motivated team, the GEM is specialized in carry out small and medium scale mechanical testing in metallic materials, welded joints and mechanical components from various industrial segments.

The health care industry is another area of activity of GEM which in partnership with BioEng routinely executes tests of orthopedic prosthesis and maxillofacial implants.

A special characteristic of the GEM is its ability to design devices and equipment for mechanical testing of various types of specimens and components even in cryogenic conditions in order to comply with specific requirements of its clients.


The Biomedical Engineering Group (BioEng), established in 2001, is dedicated to the study and analysis of some products for human health, such as orthopaedic, breast, dental and maxillofacial implants.

Since 2006, BioEng has cooperated with the Conceição Hospital Group in assessing the quality of orthopaedic prostheses and implants used in their operational units.

Since 2009, LAMEF works as official laboratory for the National Health Regulatory Agency (ANVISA) to carry out studies and analysis to evaluate the quality of prostheses, orthopaedic implants, and other products and materials for human health.

BioEng has also participated in the creation and operation of the Federal Government’s network of technological products for health services (SIBRATEC), an initiative supported by the Ministry of Science and Technology. In addition, BioEng also participates in standardization activities for the technical committee ABNT/CB-26 Medical-Dental-Hospital.


The Proeng CDT has started its activities in late 2003 at the location Cadetec.

With an impressive laboratorial infrastructure and a highly qualified and motivated team, the Proeng CDT has specialized in the mechanical evaluation and qualification of components from the various segments of the industry.

In fact, some of the tests for the automotive industry have been accredited by the Brazilian Institute of Metrology (INMETRO).

Friction welding is another area of interest for the Proeng CDT which dominates different variants of this solid state joining process, highlighting the welding of pipes for the oil and gas sector.

Finally, an important characteristic of the Proeng CDT is its capacity of designing and building its own equipment and fixtures, which opens the possibility of customizing tests according to specific requirements of its clients.


The Subsea Technology Group (TS) was founded in 2010 to carry out research and development of equipment for the offshore oil and gas industry, especially for subsea application.

Currently TS works on different areas from the development of mechanical and structural projects and finite element analyzes to the execution of full-scale tests, automation and servo-hydraulic control, selection and qualification of materials.

The group consists of a multi-task team to meet the need of multidisciplinary projects, characteristic of the oil and gas sector.

The link created with the Petrobras Research Center (CENPES) through research projects enabled the group to specialize in qualification tests of subsea pipelines like flexible and rigid risers and umbilicals. Besides the technical services basically related to mechanical testing of engineering components, TS is also active in the development of subsea equipment and accessories.


ProEng EC works directly in research, development and qualification of new components and technologies for the oil and gas, naval, railway and automotive sectors.

With a robust internally developed infrastructure, the group executes engineering projects, design of structures and prototypes, mechanical testing and also works on qualification of subsea pipes (flexible and rigid) and their accessories, such as marine floating hoses, control and power umbilicals, pipelines e automotive components.

Composed by a team of undergraduate and graduate engineering students, the ProEng EC carries out various projects of scientific and technological nature in partnership with major regional, national and multinational companies.


The Corrosion Testing Group started its activities in mid 2003 with the development of research in corrosion fatigue. One of the main characteristics of GECOR was from the beginning the development of tests and specific devices for every need, always seeking solutions to bring the theory closer to the real service situations.

GECOR was consolidated in 2004 with the first research project in partnership with Petrobras, involving studies of corrosion fatigue in welded joints of rigid risers in aggressive media saturated with CO2 gas.

Since then new topics of research involving hydrogen embrittlement have been developed as well as on stress corrosion cracking, fracture toughness and sulphide stress cracking.

Currently, GECOR also carries out fatigue tests on media containing H2S under high pressure and temperature, simulating severe application conditions.


GEND has an excellent technical staff dedicated to the development of methods to inspect the structural integrity of components and characterize materials through the use of advanced techniques of non-destructive testing and residual stress analysis. The group also supports the other groups in any needs regarding instrumentation of samples.

The main lines of work are: acoustics (conventional ultrasound, TOFD, phased array, guided waves, vibration and acoustic emission), magnetism (eddy currents, barkhausen noise and EMATs) and residual stress analysis (drill hole method, Sachs, micro-magnetic measurements and X-ray diffraction).

Amongst the infrastructure and equipment available in Gend, we can highlight the X-ray equipment Seifert Charon XRD M and the tridimensional workbench with laser interferometers. The group also develops advanced instrumentation and hardware, signal processing and analysis software, finite element simulation of the NDT techniques and in a smaller scale projects with robotics and automation.
