Ice fracture and cracks


we have been made aware of a very convincing phone scam that is focusing on our workshop participants. Participants may be contacted by phone by a firm called Business Travel Management to arrange accommodation for workshops and/or programmes.  This includes a request to enter credit card information.

Please note, INI will never contact you over the phone requesting card details. We take all payments via the University of Cambridge Online store

If you have been contacted by this company please contact us as soon as possible.

    Workshop Theme

    Broadly speaking, the fracture of sea ice occupies three settings: downscale (sea ice mechanics), mesoscale (the marginal ice zone, MIZ) and upscale (sea ice dynamics). At the downscale, the primary motivation is ice-structure interaction with a sea ice cover that may be deformed, discontinuous, comprised of pressure ridges, rafted ice, ice rubble and discrete ice floes.

    At the mesoscale, the steady increase in the width of the MIZ (apparently caused by global warming), is unexplained by present wave-ice knowledge; the breakup of sea ice floes and aggregates of floes is the subject of intense study. At the upscale, the primary motivation is the development of continuum models of sea ice rheology suitable for inclusion within regional or global climate models, and the challenge is to accurately forecast the extent of sea ice in the Arctic (which is steadily declining), and in the Antarctica, which has recently recorded three record sea ice extents 2013-2015 (a reverse trend). At this workshop, the focus is on the roles of fracture mechanics and damage mechanics in the breakup of ice shelves, river and sea ice breakup, ice-structure indentation, FEM-DEM models, probabilistic models, crack nucleation, hydrofracture, refrozen leads, ice edge failure processes, brittle compressive failure, Coulombic faulting, and anisotropic sea ice dynamics.

    This workshop will foster interactions between researchers investigation cracking phenomena at different scales and practitioners interested in explanations at different scales.

    Please note members of Cambridge University are welcome to turn up and sign in as a non-registered attendee on the day(s) during the workshop and attend the lecture(s). Please note that we cannot provide you with any support including name badge, meals or accommodation.

    In addition to visiting the INI, there are multiple ways in which you can participate remotely.



    Registration Only    
    • Registration Package: £227
    • Student Registration Package: £177

    The Registration Package includes admission to all seminars, lunches and refreshments on the days that lectures take place (Monday - Friday), wine reception and formal dinner, but does not include other meals or accommodation.

    Formal Dinner Only
    • Formal Dinner: £50

    Participants on the Registration Package, including organisers and speakers, are automatically included in this event. For all remaining participants who would like to attend, such as programme participants, the above charge will apply.


    Unfortunately we do not have any accommodation to offer so all successful applicants will need to source their own accommodation.  Please see the Hotels Combined website for a list of local hotels and guesthouses.



    Lunch will be served at Wolfson Court in the Cafeteria from 12:30 to 13:30 on days that lectures take place.

    • Registration Package participants should present their badge as payment for their meal
    • Those issued with a blue Institute door entrance card can add money onto the card via the Porters' Lodge at Wolfson Court
    • Other participants must purchase their meal using their dining card via the Porters' Lodge (forms can be found on the registration desk or at the Porters' Lodge)

    Evening Meal

    Participants are free to make their own arrangements for dinner.

    Formal Dinner

    The Formal Dinner will take place on Wednesday 6th December 2017 at Christ's College. Participants on the Registration Package, including organisers and speakers, are automatically included in this event.
