A Damage Mechanics Model for Uniaxial Deformation of Ice
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A one-dimensional stress-strain relationship is developed for pure polycrystalline ice subjected to uniaxial compression. The model is based on the continuous damage theories and includes the ...
Three-Dimensional Analysis of Ice Sheet Indentation: Lower-Bound Solutions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The methods of plastic limit analysis are used to determine the indentation pressures of a flat rigid punch on a columnar ice sheet. The ice sheet is idealized as a semi-infinite layer of ...
Limit Analysis of Ice Sheet Indentation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The methods of plastic limit analysis are used to determine the indentation pressures of a flat rectangular punch on an ice sheet. The ice sheet is idealized as a semi-infinite layer of ...
Propagation of Continuum Damage in a Viscoelastic Ice Bar
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An initial value problem of a semi-infinite nonlinear viscoelastic bar is solved with continuum damage evolution. The evolution law of the continuum damage for a viscoelastic material is used ...
Three-Dimensional Analysis of Ice Sheet Indentation: Limit Analysis Solutions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method is presented for determining the collapse pressures of an ice sheet subjected to a uniformly distributed edge load by applying the upper-bound theorem of limit analysis. The ice sheet ...
Nonlinear Dynamic Response of a Simple Ice-Structure Interaction Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The problem addressed is the continuous indentation of a ship or offshore structure into an ice sheet. The impacting ship or offshore structure is represented by a mass-spring-dashpot system ...
Failure Analysis of Impacting Ice Floes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Failure analysis of an ice floe impacting on a fixed arctic offshore structure has been carried out. The ice floe has been idealized to be an edge-loaded, inertia-driven, thin circular disk ...
