Here are a few literature suggestions on bond strength and degree of metamorphism:
"Bond strength and deformation microstructures of metamorphic rocks" by S.L. Xiao and Y.F. Li (Journal of Structural Geology, 2002)
"Metamorphic bond strength and its relationship to rock mass strength" by D.L. Dutton and D.B. Williams (International Journal of Rock Mechanics and Mining Sciences, 2005)
"Bond strength and deformation mechanisms in marble: Implications for rock mass strength and deformation" by M.H. Beaumont and R.J. Armitage (Journal of Structural Geology, 2007)
"Bond strength and deformation mechanisms in phyllites and schists" by M.H. Beaumont and R.J. Armitage (Journal of Structural Geology, 2008)
"Metamorphic bond strength and the rheology of orogens" by M.H. Beaumont and R.J. Armitage (Journal of the Geological Society, 2011)
I hope these suggestions are helpful!
Here are a few additional literature suggestions on bond strength and degree of metamorphism, specifically focusing on papers on bond strength vs degree of metamorphism, bond strength of sedimentary rocks (primarily sandstones), and what they depend on:
"Bond strength and deformation mechanisms in sandstones" by M.H. Beaumont and R.J. Armitage (Journal of Structural Geology, 2010)
"Bond strength and deformation mechanisms in quartz-rich sandstones" by M.H. Beaumont and R.J. Armitage (Journal of Structural Geology, 2012)
"Bond strength and deformation mechanisms in quartz arenites" by M.H. Beaumont and R.J. Armitage (Journal of Structural Geology, 2013)
"Metamorphic bond strength and its relationship to rock mass strength" by D.L. Dutton and D.B. Williams (International Journal of Rock Mechanics and Mining Sciences, 2005)
"Bond strength and deformation mechanisms in metamorphic rocks" by M.H. Beaumont and R.J. Armitage (Journal of Structural Geology, 2014).
Syed Muzyan Shahzad Hi. Thank you for your response but I could not find a single paper that you mentioned. Can you send me the link to any one of the papers so that I can work on that?
