A non-associative macroelement model for vertical plate anchors in clay

نویسندگان

چکیده

This work proposes a new plastic-hardening, non-associative macroelement model to predict the behaviour of anchors in clay for floating offshore structures during keying and up peak load. Building on available models anchors, non-associated plastic potential is introduced improve prediction anchor trajectory loss embedment at conditions large range padeye offsets different pull-out directions. The proposed also includes displacement-hardening rule simulate force displacement mobilisation early stages process. challenged validated against sets numerical centrifuge data. extensive validation process revealed that two four newly parameters assume constant value simulated cases. suggests only may need be calibrated use practice.
