This work addresses the early stages (≤1000 h) of dissolution corrosion behavior 316L and DIN 1.4970 austenitic stainless steels in contact with oxygen-poor (CO < 10−8 mass%), static liquid lead‑bismuth eutectic (LBE) at 500 °C for 600–1000 h. The objective this study was to determine relative early-stage resistance uncoated assess protectiveness select candidate coatings (Cr2AlC, Al2O3, V2AlxC...

The aim of this paper is to present the advantages of using Digital Image Correlation (DIC) and Infrared Thermography (IRT) to investigate the thermomechanical behavior of aluminum at the scale of its microstructure. The study combines these complementary imaging techniques: Electron Backscatter Diffraction (EBSD) to characterise the microstructure of the sample, DIC to obtain strain fields and...

By employing a “modulated-temperature” heating programme composed of a series of heat-isotherm stages, it is possible to separate the change in dimensions of an oriented material during heating into two contributions: a thermally “reversing” component which is due to linear thermal expansion and a “nonreversing” part arising from relaxation to the disordered state on heating above Tg . Some pre...

Thermomechanical analysis of the space shuttle tile thermal protection system (TPS) subjected to damage is conducted using the finite element method. The thermal and structural response of the damaged configurations are compared with the undamaged configuration to determine the relative effects of damage on the thermal protection capability and the induced thermal stresses in the TPS. The TPS i...

The linear theory of thermoelastic damping (TED) has been extensively developed over the past eight decades, but relatively little is known about the different types of nonlinearities that are associated with this fundamental mechanism of material damping. Here, we initiate the study of a dissipative nonlinearity (also called thermomechanical nonlinearity) whose origins reside at the heart of t...

Purpose Thermomechanical behavior of intermediate-size beam-to-wall assemblies including Glulam-beams connected to cross-laminated timber (CLT) walls with T-shape steel doweled connections was investigated at ambient temperature (AT) and after during non-standard fire exposure. Design/methodology/approach Three AT tests were conducted evaluate the load-carrying capacity failure modes assembly r...
