Abstract Summary
A consistent and physically accurate way of quantifying thermally-induced mechanical (TIM) strains in soils is essential to interpret non-isothermal laboratory and numerical data. Campanella and Mitchell proposed an interpretation methodology for saturated soils. However, there is as yet no accepted, clear, nomenclature for strains, leading to difficulties in distinguishing strains originating from different mechanisms. A means to interpret the volume of water that leaves soil specimens in terms of TIM strains is essential to characterise the changes in voids during non-isothermal tests. This work aims to clarify calculations, terminologies and underlying mechanisms regarding TIM strains.
