This annual report about 1999 contains information on publications, seminars and guests. In addition we have printed a list of the DCAMM reports number 1-612 including the available final references and also a list of the DCAMM S-reports number S1-S84.

The report serves mainly as reference and documentation for accomplishes activities. Information on the actual activities are available on our homepage: www.fam.mek.dtu.dk and on the homepages of the cooperating departments of the center.

In 1999 the DCAMM Graduate Research School gave 7 advanced courses: Continuum Mechanics, Finite Strain Plasticity and Fracture Mechanics, 21-29 Jan. 1999. Hamiltonian Mechanics with Applications, 14-22 Jun. 1999. Nonlinear Wave Dynamics in the Coastal Zone, 14-22 Jun. 1999. Impact Modelling of Metal Structures, 14-22 Jun. 1999. Mechanics of Composite Materials, 24 Jun. - 2 Jul. 1999. Structural Reliability and Stochastic Modeling, 9-20 Aug. 1999. Parameter Identification in Groundwater Modelling, 9-13 Aug. 1999. The school was visited by 30 Guestprofessors, 10 Gueststudents and 154 Courseparticipants, and the school continues its activities in year 2000.

Also this year, I thank our international contacts for their support and inspirations.
