Geomaterials, such as soil, rock and concrete, are multiphase porous materials whose macroscopic mechanical behaviors are governed by grain size distribution and mineralogy, fluid-saturation, pore space, temperature, loading paths and rate, drainage conditions, chemical reactions, and other factors. As a result, predicting the mechanical responses of geomaterials often requires knowledge on how several processes, which often take place in different spatial and temporal domains, interact with each other across length scales.

This mini-symposium is intended to provide a forum for researchers to present contributions on recent advances in computational geomechanics problems. Topics within the scope of interests include: development and validation of constitutive models that address coupling effects, discrete and continuum formulations for hydromechanics and thermo-hydro-mechanics problems, iterative sequential couplings of fluid and solid solvers, spatial variability of soil properties, multiscale mechanics, numerical enhancement techniques such weak and strong discontinuities, and regularization techniques to circumvent pathological mesh dependence.
