Many living organisms, particularly plant tissues, exhibit very interesting features with regard to technical applications. For example, many plant tissues are frost resistant, which is mainly due to the dehydration of their tissue cells as one of the crucial mechanisms to cope with subzero temperatures. In this contribution, a fully coupled thermo‐hydro‐mechanical model based on the Theory of Porous Media is applied to assess the impact of ice formation on the water content of the tissue cells. Special attention is paid to the water exchange from the cells to the macro‐pore space.
