Abstract
Geotechnical considerations are important in identifying the conditions leading to instability of seabed-offshore-structures under waves. It is necessary to model such soil behavior via theoretical frameworks. This paper summarizes the fundamentals of constitutive modeling of cyclic seabed behavior. Two main theories namely, bounding surface plasticity and generalized plasticity theory are introduced for both granular and cohesive soils. Modeling considerations to evaluate the elasto-plastic soil response in terms of governing equations of elemental behavior are presented. Finally, verification of theoretical results through classical tests is presented to demonstrate the accuracy of constitutive modeling of cyclic behavior of seabed around coastal structures.
