A numerical model for compressive coneshaped ice tests was developed using LSDYNA • A crushable foam with failure criteria was adopted to simulate a spalling event • Evaluation of scalability up to 25 times larger size was performed • The numerical model was verified from the viewpoint of global load and local load

A numerical model of ice crushing using a foam analogue By R E Gagnon Cite BibTex Full citation Abstract A numerical model for ice crushing has been constructed that takes into account the physical processes identified in many experimental studies These include the presence and evolution of highpressure and lowpressure zones the

The failure of ice colliding with the structure was realized using a crushable foam material model whose detail parameters were tuned using the experimental results of an ice cone crushing test

A new numerical ice model is proposed based on a soil and concrete constitutive material model with modified ice material properties applied • The ‘DerradjiAouat’ yield surface model and a new empirical failure criterion to describe ice failure mechanical behavior is used in the proposed ice model

A numerical model for ice crushing has been constructed that takes into account the physical processes identified in many experimental studies

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

A simplified numerical model is introduced to predict ice impact force acting on the ship hull in level ice condition The model is based on icehull collision mechanisms and the essential ice

These limitations make the numerical simulation of icestructure interactions a challenge In the 1980’s the typical numerical methodology to model iceberg ice was based on the use of simplified analytical equations and ice failure strength eg Cammaert and Tsinker and Arockiasamy et al The crushing and crack of iceberg ice during

An efficient model of particle breakage is applied to perform a large number of tests in which grading evolution is continuously tracked using a grading index Using both previous and new experimental results the discreteelement model is calibrated and validated to represent Fontainebleau sand a

Numerical simulations of a collision between a loaded tanker and a bergy bit have been conducted using LSDyna software The simulations incorporated hydrodynamics via LSDynas ALE formulation and a validated crushable foam ice model The major portion of the vessel was treated as a rigid body and a section of the hull located on the
