STRUCTURAL INTEGRITY AND MATERIALS DESIGN LABORATORY


The Structural Integrity and Materials Design (SIMD) Laboratory studies the mechanical behaviour of structures and structural components in operating conditions. Researchers analyze the causes of degradation processes in structural materials.

The Laboratory has a range of tensile testing equipment used to determine strength and local mechanical characteristics using miniature specimens. There is also equipment for testing the strength of real-size structural components. Besides performing standard hardness tests, the Laboratory is also able to determine micro- and nanohardness in localized volumes of material. Resistance to crack propagation in structures at real stress states is determined by toughness testing under quasistatic and dynamic loading. Stress deformation characteristics and toughness characteristics are used to calculate the lifespan of structures operating at extremely high or low temperatures, under conditions of high-speed dynamic impact or under time-variable loading. Microstructural causes of material damage are studied using optical, confocal or scanning electron microscopy techniques. The Laboratory compiles expert reports on the causes of damage to structures and structural components; researchers also recommend measures for extending service life and optimizing safety.
