A plasticity model describing caisson behaviour in clay

Capacity of modified suction caissons in marine sand under static horizontal loading

“…Currently, the popular methods to research the horizontal capacity of the regular suction caissons are focused on model tests (Watson and Randolph, 1998;Byrne and Houlsby, 1999;Watson et al, 2000;Cassidy et al, 2004;Zhu et al, 2011;Gao et al, 2013;Ibsen et al, 2013a,b), numerical modeling (Bransby and Randolph, 1998;Gourvenec, 2008) and the theoretical methods such as limit equilibrium, elasticity and plasticity modeling (Cassidy et al, 2006).…”

An Experimental Study of the Drained Capacity of Suction Caisson Foundations Under Monotonic Loading For Offshore Applications

“…3, (ii) a ‰ow rule to describe the incremental plastic displacements at yield, (iii) a description of the elastic behaviour within the yield surface, and (iv) a hardening law to deˆne the expansion or contraction of the yield surface. For further discussion of this framework see Nova and Montrasio (1991), Martin (1994), Cassidy (1999), Gottardi et al (1999), Martin andHoulsby (2000, 2001), Byrne and Houlsby (2001), Houlsby and Cassidy (2002) and Cassidy et al (2002Cassidy et al ( , 2004Cassidy et al ( , 2006. This paper deals with the experimental study of theˆrst three components of the model.…”

Model testing of upright and tapered suction caissons in sand

“…Email: zeinoddini@kntu.ac.ir caissons with regard to their applications, installation, loadbearing, etc. has already been investigated by a number of researchers (Bang et al 2000;Cassidy et al 2006;Narasimha Rao et al 2006;Zeinoddini et al 2010). Some previous numerical investigations indicated that positively tapered suction caissons may provide pull-out capacities considerably higher than that of their equivalent upright caissons Zeinoddini et al 2008a;Zeinoddini et al 2008b;Zeinoddini, Hobbi, et al 2009;Zeinoddini, Keyvani, et al 2009).…”
