Caulfield Engineering’s professional staff has over 100 years of combined accident investigation experience. Whether the assignment is a plumbing failure, a chemical plant accident, or a boiler explosion, Caulfield Engineering has the technical and investigative skills to determine what happened as well as manage, document, and retain evidence for any size or type of site.
Documenting an undisturbed scene is critical to the preservation of evidence for scientific analysis. Caulfield Engineering’s scientists, engineers, and technicians have decades of experience using precision measurements and scene documentation. Our state-of-the-art equipment includes laser scanners and total stations, and scene data can be exported for CAD drawings, surveying, dimensional analysis, modeling, and visualization.
Photogrammetric analysis is the practice of combining mathematics, geometry, and physics to transform perspective imagery into three-dimensional measurements and models. Typical subjects of photogrammetric analysis include busy roadways, biohazard zones, compromised structures, and restricted-access locations, as well as subjects and scenes which have not been preserved.
Failure analysis involves the utilization a variety of scientific techniques to carefully investigate and gather information concerning the Who, What, When, Where, and How of a failure. Engineering and technical experts analyze the accident including the machine or equipment involved, the accident site and environmental factors, materials used for the fabrication of components, and the human interactions and inputs related to the accident.
The chemical resistance of metals, plastics, and elastomers can be affected by concentration, temperature, presence of other chemicals and other factors. Caulfield Engineering is well suited to conduct initial literature reviews to provide preliminary guidelines, and if desired, proceed further with more extensive laboratory experimentation.
Materials utilized to build homes and commercial buildings are often the subject of projects Caulfield Engineering encounters. When these materials do not perform as intended, effects can range from concerns over toxin exposure of building occupants to damages caused by water intrusion.
When a product in the marketplace does not function as intended, the consequences can be wide-ranging and at times devastating. Certain defects cause failures that result in a product failing prematurely. Other defects result in dangers to the consumer ranging from fire causation to toxin exposure. Our expertise in manufacturing and evaluation of expected properties is particularly valuable in these instances.
Caulfield Engineering has a multi-disciplinary staff with a vast array of experience in providing technical assistance in intellectual property matters. Whether it be patent analysis, trade secrets, claim construction, or questions of validity or infringement, Caulfield Engineering intellectual property experts have the knowledge to provide efficient and effective technical assistance.
Caulfield Engineering’s patent experts have extensive experience in analyzing questions of patent validity. Our staff can assist in prior art searches and perform validity analysis of patent claims based on obviousness, anticipation, enablement, and specification support.
Metallurgical and Materials engineering is geared towards resolving the questions of why and how materials, components, and systems fail. Caulfield Engineering has the expertise to assist industries in tapping into the unlimited potential for innovation and design with materials science.
When a part or component fractures, the fracture process leaves behind characteristic topographical features on the fracture surfaces that when studied can provide critical information regarding the events that resulted in the fracture event. Fractography is the art or science of examining the fracture surface to interpret and understand these characteristic features
Mechanical testing is used to establish the expected mechanical performance of a material, such as its strength, ductility, and toughness. Caulfield Engineering’s engineers are also highly skilled in the analysis of these test results and apply the information gleaned from these results in design analysis and failure analysis investigations.
Finite element analysis is an important engineering tool for stress analysis, fracture and fatigue analysis, and design analysis of any structure. Examples of where this tool can be used include optimizing designs up front during the design process, analyzing vehicle crash performance, or performing root cause analysis of a pressure vessel explosion.
Fracture mechanics and fatigue analysis are essential to understanding the structural performance of real world materials. Fracture mechanics is the study of the complex stress field around the tip of a crack and can be used to determine if an existing crack will propagate or arrest. Fatigue analysis is the study of the fracture behavior under repeated cyclic loading.
Structural analysis is the determination of the forces within elements of trusses, frames, space structures, and machinery resulting from applied loads or displacements. Our computational resources in this field include among others the Abaqus Finite Element Analysis product suite and the MATLAB multi-paradigm numerical computing environment.
Modern life in the global world revolves around transportation in numerous forms. Whatever type of vehicle, Caulfield Engineering can understand the complexities of the system. Our experience with transportation equipment includes nearly every aspect of the product lifecycle.
Documenting the location, orientation and condition of all of the evidence at a loss scene is of the upmost importance before the scene is disturbed. Caulfield Engineering can capture and document a scene, digitally preserve it, and prepare a digital map of the scene and its evidence.
