Abstract: The dynamic response of a tension leg platform is studied using spectral analysis techniques. Equations of motion are derived for the rigid platform and its legs which are idealized as cables ...

Abstract: A method is developed for optimizing the size of a tension leg platform (TLP) and its tethers so as to minimize the weight-based cost of the TLP system subject to various design constraints. ...

Abstract: The lower and upper bound theorems of plastic limit analysis are extended to a stochastically inhomogeneous medium. The extended theorems provide bounds on the mean safety factor against plastic ...

Abstract: The basic equations for nonplanar transverse vibrations of marine risers are derived from the theory of elastic rods. A numerical method is developed for solution of the equations by time ...

Abstract: This paper contains an analysis of the free vibrations of uniformly pretwisted rectangular plates, utilizing the exact equations of classical shallow-shell theory. Specifically, solutions are given ...

Abstract: The plane problem of a rigid stamp on a truncated wedge of rigid/perfectly plastic material is solved by the method of characteristics for a generalized von Mises yield function. Quadratic ...

Abstract: A computational method is developed for the finite-amplitude three-dimensional motion of inextensible elastic rods with equal principal stiffnesses. The method also applies to the two-dimensional ...

Abstract: This paper is concerned with the finite twisting and expansion of an annular rigid/plastic plate in the state of plane stress. The plate, bounded by two concentric circles one of which may ...
