Abstract
Geotechnical engineering has conventionally emphasized macro-scale phenomena in soil and rock mechanics.
Nonetheless, the latest progress in nanotechnology has unlocked fresh opportunities to investigate the behavior
of geomaterials at the nanoscale. This emerging field, known as nano-geo-mechanics, holds great promise for
enhancing our understanding of fundamental geotechnical processes and developing innovative solutions for
geotechnical engineering challenges.
This paper provides an overview of the challenges associated with the application of nano-geo-mechanics in
geotechnical engineering. It discusses the scale dependence of friction in geomaterials, highlighting the complex
interplay of surface roughness, interfacial interactions, and atomic rearrangements. The computational
complexity associated with atomistic simulations, such as molecular dynamics, is also addressed, considering
the large number of atoms present in geomaterials and the need to simulate their behavior over relevant time and
length scales. To address these challenges, a comprehensive understanding of nano-geo-mechanics requires a
multidisciplinary approach that combines experimental investigations, advanced characterization techniques,
theoretical models, and computational simulations. Continuous research endeavors seek to create precise
predictive models for nano friction in geomaterials, enhancing our comprehension of essential geotechnical
processes and laying the groundwork for groundbreaking applications in geotechnical engineering. This article
underscores the significance of nano-geomechanics in geotechnical engineering and serves as a valuable
reference for researchers and practitioners keen on exploring the opportunities and obstacles in this emerging
domain. By addressing these challenges, nano-geo-mechanics has the potential to revolutionize geotechnical
engineering, leading to more sustainable and efficient geotechnical solutions.
