Failure Analysis

Using our engineering analysis tools such as optical microscopy, energy dispersive spectroscopy, optical emission spectroscopy, scanning electron microscopy and metallography among other techniques we are able to determine the root cause of component and structures failures. Combining those techniques with the state-of-the-art finite element analysis and materials mechanical characterization we additionally can suggest modifications in the engineering project in order mitigate the potential of future failures.

Metallurgical characterization

The cause of failure of a particular component or structure may be related to an error in material specification or even due to a processing problem that results in an unfavorable metallurgical condition. Thus, it is a routine procedure in failure analysis the metallurgical characterization of the materials involved. In LAMEF, we have a complete infrastructure for metallography and microstructural evaluation of ferrous and non-ferrous alloys, scanning electron microscopes and even microprobes and optical emission spectrometers for local and global chemical analysis respectively.

MATERIALS TESTING

Materials need testing to assess product quality, functioning, safety and reliability.

Effective materials testing covers verification of material characteristics for application trials, detection of defects, analysis of failures and improvement of new materials. Our materials testing services offer you comprehensive testing for metals, polymers and composites. Using the state-of-the-art equipment we can fully mechanically characterize engineering materials for the various sectors of the industry. We can carry out a wide range of material testing methods including static tensile, compression, bending, fatigue, impact, fracture toughness and environment assisted cracking.

FINITE ELEMENT ANALYSIS (FEA)

In the late 1950s and early 1960s a method was proposed for solving partial differential equations. The finite element method (FEM), as it is known, emerged from the need to solve complex structural analysis problems in engineering and consists in the discretization of a continuous domain by “n” finite elements.

In LAMEF, the finite element method (FEM) is applied for structural development and optimization of components, test rigs and also to predict the mechanical behavior of industrial components, such as oil and gas pipelines, sleeve repairs of rigid pipelines, flexible pipeline structures, shackles, hooks and chains used for offshore production units anchoring.

In order to represent real operational conditions with a high level of accuracy, FEM results are calibrated and validated through real components testing, with monitoring systems composed by strain gages, optical fibers, acoustic sensors, accelerometers and photoelasticity. Validation methods are used to ensure model precision so that is possible to reduce further mechanical tests.
