Structural mechanicsStructural mechanics or mechanics of structures is the computation of deformations, deflections, and internal forces or stresses (stress equivalents) within structures, either for design or for performance evaluation of existing structures. It is one subset of structural analysis. Structural mechanics analysis needs input data such as structural loads, the structure's geometric representation and support conditions, and the materials' properties. Output quantities may include support reactions, stresses and displacements.
Calcul des structures et modélisationLe calcul des structures et la modélisation concernent deux domaines distincts : d'une part les applications spécifiques au patrimoine architectural, mobilier et naturel et d'autre part les applications industrielles. Le calcul des structures et leur modélisation est utilisé dans les domaines : de la conservation et mise en valeur du patrimoine architectural, mobilier et naturel, dans le cadre de missions d’assistance à la maître d’œuvre ou au maître d’ouvrage permettant d’arrêter un programme de travaux, d’applications industrielles.
Mécanique (technique)La mécanique en tant que technique ou activité industrielle, est l'ensemble des activités, méthodes et techniques liées à la conception de structures (charpentes, coques, bâtis), machines ou de mécanismes. Ces activités regroupent l'étude, la conception, la fabrication, la maintenance et la déconstruction de toute structure ou dispositif (moteurs, véhicules) produisant ou transmettant un mouvement, une force, ou une déformation.
Ingénierie des structuresL'ingénierie des structures est un domaine de l'ingénierie et plus particulièrement du génie civil, traitant de la stabilité des constructions (conception et de l'analyse des structures). Une structure est soumise à différentes actions, permanentes ou variables dans le temps, statiques ou dynamiques, de nature mécanique ou thermique, et sa conception vise à satisfaire certains critères vis-à-vis de ces actions : Sécurité : sa résistance, son équilibre et sa stabilité doivent être assurés avec une probabilité choisie ; Performance : son fonctionnement et le confort associés doivent être garantis pour une durée suffisante ; Durabilité : la dégradation de la structure dans le temps doit être limitée et maîtrisée pour satisfaire les deux premiers critères.
Structural engineerStructural engineers analyze, design, plan, and research structural components and structural systems to achieve design goals and ensure the safety and comfort of users or occupants. Their work takes account mainly of safety, technical, economic, and environmental concerns, but they may also consider aesthetic and social factors. Structural engineering is usually considered a specialty discipline within civil engineering, but it can also be studied in its own right.
Structural integrity and failureStructural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs. Structural integrity is the ability of an item—either a structural component or a structure consisting of many components—to hold together under a load, including its own weight, without breaking or deforming excessively.
Engineering design processThe engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative - parts of the process often need to be repeated many times before another can be entered - though the part(s) that get iterated and the number of such cycles in any given project may vary. It is a decision making process (often iterative) in which the basic sciences, mathematics, and engineering sciences are applied to convert resources optimally to meet a stated objective.
Ingénierie des systèmesL'ingénierie des systèmes ou ingénierie système est une approche scientifique interdisciplinaire, dont le but est de formaliser et d'appréhender la conception et la validation de systèmes complexes. L'ingénierie des systèmes a pour objectif de maîtriser et de contrôler la conception de systèmes dont la complexité ne permet pas le pilotage simple. Par système, on entend un ensemble d'éléments humains ou matériels en interdépendance les uns les autres et qui inter-opèrent à l'intérieur de frontières ouvertes ou non sur l'environnement.
Process engineeringProcess engineering is the understanding and application of the fundamental principles and laws of nature that allow humans to transform raw material and energy into products that are useful to society, at an industrial level. By taking advantage of the driving forces of nature such as pressure, temperature and concentration gradients, as well as the law of conservation of mass, process engineers can develop methods to synthesize and purify large quantities of desired chemical products.
Process designIn chemical engineering, process design is the choice and sequencing of units for desired physical and/or chemical transformation of materials. Process design is central to chemical engineering, and it can be considered to be the summit of that field, bringing together all of the field's components. Process design can be the design of new facilities or it can be the modification or expansion of existing facilities. The design starts at a conceptual level and ultimately ends in the form of fabrication and construction plans.
Engineering managementEngineering management is the application of the practice of management to the practice of engineering. Engineering management is a career that brings together the technological problem-solving ability of engineering and the organizational, administrative, legal and planning abilities of management in order to oversee the operational performance of complex engineering-driven enterprises. A Master of Engineering Management (MEM) is sometimes compared to a Master of Business Administration (MBA) for professionals seeking a graduate degree as a qualifying credential for a career in engineering management.
