As part of the experimental program, techniques to use pressure measurement film were adopted to obtain ice-structure contact location, actual contact area, and changes of magnitude of pressure within the contact region. Following the experimental program a numerical model of ice crushing for concave surfaces was developed.

Failure Analysis Case Studies Ⅱ

A numerical model for compressive cone-shaped ice tests was developed using LS-DYNA ®. • A crushable foam with failure criteria was adopted to simulate a spalling event. • Evaluation of scalability up to 2.5 times larger size was performed. • The numerical model was verified from the viewpoint of global load and local load.

A numerical model has been derived which is then compiled on FORTRAN to develop a simulator for the production of shale gas by considering the spheres as a source term in each of the grid blocks. By applying SiC to field data, we demonstrate that the model provides an effective way to quickly access gas production rates from shale formations.

The objective of this study is to investigate ice-structure interaction and develop a numerical model to predict the changes of ice loads and pressure during ice-structure interaction on non-planar surfaces. It is important to understand the sequential ice pressure and load development during ice-structure interaction. This is particularly true for non-planar surfaces as most ships and many ...

A simplified 2-DOF vehicle model was considered as the analytical model, and a rear suspension ADAMS model with the hydraulic pulse actuator was developed. Secondly, the effect of the steering system on vehicle stability was studied and the pulse signal parameters (frequency and amplitude) were evaluated to determine their optimum values.

For application to exploration under the surface of icy objects in the solar system, the penetration of an impact probe into an icy target was experimentally simulated by using the ballistic range. Slender projectiles with a cylindrical body and various nose shapes were tested at the impact velocity 130 - 420 m/s. The motion of the penetrator, fragmentation of ice and crater forming were ...
