ANNOUNCEMENTS INTERNATIONAL
SYMPOSIUM
ON STRUCTURAL
FAILURE
to be held at Massachusetts Institute of Technology, Cambridge, Massachusetts, U.S.A. Little Kresge Auditorium 6-8 June 1988
Objectives and background The objective of the Symposium is to present a state-of-the-art summary in failure analysis of engineering structures subjected to extreme or accidental loadings; to highlight the areas of difficulty and to indicate ways forward for improvement in our predictive capabilities. Emphasis will be placed on the interaction effects between localized failure (folding and tearing) and overall structural response. It is recognized that the currently available analytical and numerical techniques for tackling micro and macro aspects of predominantly ductile failure are restricted to some very specialized situations. Simple and reliable engineering methods are needed to determine the amount of damage caused to a ship by missile impact, or to predict the loading conditions that may lead to the breakup and fragmentation of a space vehicle. New techniques are also required to improve the collision protection of land and sea vehicles or to determine residual strength of partially damaged onshore and offshore structures. Finally, the failure pattern of structures made of composite materials should be better understood. The first of the present series of conferences entitled "Structural Crashworthiness" was held in 1983 in Liverpool. This highly successful Symposium was documented by a book entitled Structural Crashworthiness, edited by N. Jones and T. Wierzbicki. In addition, 15 contributing papers were accommodated in 25 (9, 10) (1983) of the International Journal o.1" Mechanical Sciences and 1 (3) (1983) of the International Journal of Impact Engineering. As the title suggests, emphasis in the first Symposium was put on failure due to predominantly compressive loads (plastic collapse and folding). The present, second symposium emphasizes the difficult subject of tension induced failure (shearing, tearing, breakup and fragmentation, etc.). Crashworthiness remains a sub-topic.
Scope The scope of the Symposium has been restricted to "Structural Failure" as opposed to "Material Failure". Consequently, damage mechanics, i.e. the micro-mechanical aspect of failure such as nucleation, growth and linkage of micro-cracks or voids, has not been included in the scope of the present Symposium, nor is constitutive modelling considered as a Symposium topic. Also, we have excluded those aspects of failure which have evolved into separate and welldefined fields, such as "Linear Fracture Mechanics", "Fatigue", "Corrosion", "Buckling", etc. However, the applications of the constitutive equation to predict localization, through thickness failure, shear bands, etc., remains an important Symposium topic. The following subject areas indicate the scope of the 3-day Symposium. General concepts and methods. Localization, necking, deformability limits, crack initiation, application of strain softening. Failure under high rate of loading. Hydrodynamic effects, fragmentation. Quasi-static and dynamic rupture and tearing of shells. Crush prediction of sheet metal structures. Structural failure of composites. System failure (effect of failure of one element on overall structural response). -

Symposium publications
The Symposium will be documented by a book entitled Structural Failure, edited by T. Wierzbicki and N. Jones, and published by John Wiley Inc. The 425 page book will contain 15 invited lectures arranged in four subject groups, which arc as follows.
Part (1) (2) (3) (4)
I -- Failure Under Quasi-Static Loading Tearing of Thin Metal Sheets. Modelling of Thin-Walled Structures for Crush. Denting and Bending of Tubular Beams Under Local Loads. Failure of Fiber Reinforced and Woven Materials by Numerical Methods.
Part (5) (6) (7) (8) (9)
II -- Failure Under Medium Rate of Loading (Inertia E[,]ects) Energy Absorption of Composite Structures. Performance of Stiffened Compositional Metallic Panels Under Air Blast Loading. Dynamic Bending Collapse of Strain-Softening Beams. Dynamic Tearing and Shearing Failure of Beams. Dynamic Rupture of Shells.
Part (10) (11) (12)
III -- Failure Under High Rate of Loading Dynamic Fragmentation. Controlled Fracturing of Structures by Shock Wave Interaction and Focusing. Debris Impact Protection of Space Structures.
Part (13) (14) (15)
I V -- System Failure Structural Failure Under Repeated Loads. Catastrophic Failure Modes of Marine Structures. Industrial Experience with Structural Failure.
In addition to the book, some 15-20 contributing papers will be accommodated in special conference issues of the International Journal of Mechanical Sciences and the International Journal of Impact Engineering. It is our intention that both the book and journals will be printed before the Symposium starts and available at the Registration Desk.
CALL FOR PAPERS Original, contributing papers are sought in the subject areas defined by the scope of the Symposium. Papers should meet the style, format and length requirements of either the International Journal of Mechanical Sciences or the International Journal of Impact Engineering. Papers will be subject to a regular, albeit somewhat accelerated, review process. There will be no pre-selection process of conference papers. Full manuscripts should be sent directly to Professor Norman Jones, co-Chairman of the Symposium and Technical Editor of the International Journal of Impact Engineering no later than 15 October 1987. A separate copy should be sent to Professor T. Wierzbicki, co-Chairman of the Symposium. Papers received after that date may appear in later issues of the above mentioned journals. However. authors are encouraged to forward their contribution as early as possible as only a limited number of 15-20 papers can be accommodated in the special Symposium issues of the journals and in the Symposium program. Accommodation A block reservation has been made at the Hyatt-Regency Hotel in Cambridge for Symposium participants. Inexpensive accommodation will also be available in dormitories on the MIT campus.
