Understanding the behavior of materials in their environment
During their life cycle, the properties of structural materials change. Their implementation involves thermochemical and/or mechanical processes. This induces initial stresses and even which is also influenced by early physical-chemical and mechanical loading. During the service life of the structure, the materials continue to evolve under the effect of environmental actions and mechanical stresses. In modern structural design codes, the service life of structures is defined as the period of serviceability. In an engineering approach, this implies to control the ageing of materials or their durability, so that they provide the structure with the expected level of reliability throughout its life. Taking into account the social issues associated with the various stages of the life of materials and structures implies innovations or even technological breakthroughs (link with the TRU “Green engineering approaches”), in the composition of materials used (low-carbon materials, recycled materials, biobased materials, etc.) and processes.
The objective of the TRU Processes and durability of materials and structures (DURPRO) is to understand and predict the evolution and life span of existing and future structures. Its originality consists in studying the relationships between the composition, the implementation processes and the durability of materials. The approaches developed in the TRU are based on experimentation and modeling and consider in particular the couplings between physical-chemical and mechanical stresses.
