This fact poses serious limitations on the formulation of a materially objective soil constitutive theory, based on experimentation performed on earth. In particular, the presence of the earth's gravity prohibits the design of controlled experiments to properly simulate a variety of critical phenomena associated with the dynamic response of soils to seismic excitation in a very low effective confining stress field. For these reasons, the advent of the space age and, more specifically, the capabilities of the Space Shuttle-Spacelab for several day experimentation by trained specialists in a "shirt-sleeve," laboratory-controlled environment, under essentially zero-gravity conditions, could offer invaluable opportunities for developing a quantitative understanding of fundamental aspects of soil behavior during and after an earthquake, which, in turn, could result in significant technological advances in geotechnical earthquake engineering.

The undrained stress-strain, strength, and pore water pressure responses were measured during cyclic loading events that simulated conditions existing under the platform when subjected to realistic storm wave loading.

The journal remains among the largest ASCE journals in terms of the number of papers published, as well as being among the most visible and productive mechanics journals based on readership, impact, and citations. The number of manuscripts submitted has continuously grown over the years, and in 2001 the number was 344. The total number of papers published during the 12 months ending in May, 2002, was 156. Nearly one-half of the papers published come from overseas, which is a particular testimony to the international nature of the journal and mechanics in general. The journal receives a constant stream of high quality papers, and we expect this trend to continue. During the past 5 years, we have devoted on the average two issues each year to special topics to stimulate readership and authorship in related fields of mechanics with the expectation to grow the journal in these areas. While the performance indicators and statistics for the journal are generally very favorable, the Editorial Board members and I are concerned that a large number of reviews are long overdue, which does not reflect well on the journal and often frustrates talented authors, who may publish their papers elsewhere. It is very important that our authors know that the journal will process their papers quickly and fairly, and at the same time provide meaningful reviews. Another area of grave concern is the increasing number of cases involving multiple paper submissions and publications, which both violate the integrity of the journal and copyright agreements. In recent cases, the journal has barred offending authors from publishing for a period of 10 years. Clearly, the journal is deeply concerned about these developments and is making major efforts to address the issues. This year marks ASCE’s 150th anniversary, and the journal is joining the celebration by publishing three invited papers by outstanding scholars in the field of mechanics in separate issues this fall. The subjects range from past achievements, state-of-the-art reviews, and future trends. As Editor, it has been my very good fortune to witness firsthand many new exciting developments in mechanics, both in terms of theory and experiments. This has been one of the most rewarding and exciting tasks I have had, and I thank you so much for the opportunity to serve the broad mechanics community. As I bid you farewell, please join me in welcoming the new Editor, Professor Mircea Grigoriu from Cornell University, who officially takes over on October 1, 2002.

However, development of large deformation elastic}plastic numerical formulation for dilatant, pressure sensitive material models is still a research area. In this paper we present development of the "nite element formulation and implementation for large deformation, elastic}plastic analysis of geomaterials. Our developments are based on the multiplicative decomposition of the deformation gradient into elastic and plastic parts. A consistent linearization of the right deformation tensor together with the Newton method at the constitutive and global levels leads toward an e$cient and robust numerical algorithm. The presented numerical formulation is capable of accurately modelling dilatant, pressure sensitive isotropic and anisotropic geomaterials subjected to large deformations. In particular, the formulation is capable of simulating the behaviour of geomaterials in which eigentriads of stress and strain do not coincide during the loading process. The algorithm is tested in conjunction with the novel hyperelasto}plastic model termed the B material model, which is a single surface (single yield surface, a$ne single ultimate surface and a$ne single potential surface) model for dilatant, pressure sensitive, hardening and softening geomaterials. It is speci"cally developed to model large deformation hyperelasto}plastic problems in geomechanics. We present an application of this formulation to numerical analysis of low con"nement tests on cohesionless granular soil specimens recently performed in a SPACEHAB module aboard the Space Shuttle during the STS-89 mission. We compare numerical modelling with test results and show the signi"cance of added con"nement by the thin hyperelastic latex membrane undergoing large stretching.

A key element in such analyses is the proper modeling of the constitutive behavior of soils. Intensive research in recent years has led to a proliferation of constitutive models which have been postulated to represent soil behavior under general loading conditions. In this paper some of these models are reviewed regarding their basic assumptions and the requirement of input data for their characterization. A classification of constitutive models is given on the basis of basic approaches to relating stress and strain. Representative models from each class are selected for detailed examination, with the hyperbolic model, the elastic-perfectly plastic model, the Cam-Clay model, the cap model. Lade's model, Prevost's model, and the endochronic model being selected. Finally, a comparison is made of these models regarding their range of applicability.
