mechanisms proposed from the initial discovery stage to the present were reviewed, they are mainly the dislocation mechanism, the compressive stress mechanism, the recrystallization mechanism, the cracked oxide theory and the fresh tin atom mechanism. After making some comments on the problems of the theoretical models, some further suggestion for the whisker growth mechanism were put forward. Key words......
J. Cent. South Univ. (2020) 27: 2745-2753 DOI: https://doi.org/10.1007/s11771-020-4495-7 A simple theoretical approach for analysis of slide-toe-toppling failure Hassan Sarfaraz School of Mining... by an analytical method and experimental tests. In the present study, at first, the literature review of toppling failure is presented. Then a simple theoretical solution is suggested for evaluating this failure......
