This paper is devoted to the description of a new full MLS
SPH modelisation of rupture of thin shell filled with fluid and the
prediction on consecutive fluid loss though the fracture. The paper first
presents an efficient and controlled model for elastoplastic rupture of thin
shells by a single layer of SPH balls. The proposed model controls as well
static and dynamic instabilities using two basic ingredients: additional
stress points to control the hourglass like instabilities and extend the
Monhagan viscosity control method to shear and bending components of the
generalized efforts. The fluid is modeled using standard SPH fluid model.
The interaction is modeled using pin-balls method which is very natural in
this type of formulation. Application examples are presented.
