The report describes the erection, field testing and disassembly of the LocArch air transportable aircraft shelter. The outcome of the shelter evaluation revealed the design concept to be basically sound but deficiencies existed in the arch panels and the end closures. An in depth analysis of the shelter components was conducted during the test program. The entire shelter system was subjected to simulated environmental tests to evaluate its performance for possible world wide use.

A method for the analysis of perturbations of integrable planar systems of differential equations is developed. Concentrating on the case in which the unperturbed system is Hamiltonian and the perturbation introduces dissipation and time-periodic forcing, the global solution curves of the unperturbed system are used in regular perturbation calculations to locate subharmonic orbits and homoclinic orbits and to characterize the bifurcations in which they are created as external parameters are...

The finite element solution formulation in time- and space- coordinates is extended to beam vibrations effected by a moving couple. This problem has direct application to gun motions analysis with an unbalanced moving projectile. The moving load, instead of being a time-dependent Dirac delta function as for the case of a moving concentrated force, is now the derivative of this Dirac delta function. This singular function does not present any difficulty due to the variational process employed....

A comparison between the maximum deflections resulting from beams symmetrically loaded into the elastic-plastic region is presented for the case of three and four point bending. The results indicate that significantly larger deflections can be obtained for the case of four point bending while keeping the maximum fiber strains approximately the same. It appears that using the four point bending approach holds certain advantages in straightening operations for the removal of permanent deflections...

We consider the problem of reconstructing the flexural rigidity r(x) and the density rho(x) of a beam. The unknown beam is assumed to have a free left end and a clamped right one. The data consist of the displacement and angle of the center line of the free left end following an initial impulse. The information content of this seismogram-like impulse response is equivalent to three spectra (omega sub n), (nu sub n), (mu sub n) and two gross constants F1, F2. This data do not specify the...
