ABSTRACT
It is now possible to realistically simulate cone penetration in either sand or clay using the Material Point Method (MPM). To do that, the following requirements must be met: (1) a realistic constitutive model must be used; (2) stress integration of the constitutive model must be accurate; (3) the explicit scheme for the solution of the governing equation must be accurate, robust and efficient; and (4) shear strain localization must be correctly captured. The paper provides an overview of how to correctly perform such simulations and then discusses the implications for the future of CPT interpretation of the availability of accurate, reliable cone penetration simulation methods.
