Abstract: The problem of nosing of shells in finite plastic strain is analyzed by considering various methods of jointly linearizing yield condition and flow rule. The numerical results show that excellent ...

Abstract: The Sequential Unconstrained Minimization Technique (SUMT) offers an easy way of solving nonlinearly constrained problems. However, this algorithm frequently suffers from the need to minimize an ill‐conditioned penalty ...

Abstract: The need to account for geometric and material nonlinearities in the active control of highly flexible, large, space structures is emphasized herein. The performance index of the control problem is minimized subject to ...

Abstract: The response of structural dynamical systems excited by multiple random excitations is considered. Two new procedures for evaluating global response sensitivity measures with respect to the excitation components are proposed. ...

Abstract: The problem of determining the probability distribution function of extremes of Von Mises stress, over a specified duration, in linear vibrating structures subjected to stationary, Gaussian random ...

Abstract: The problem investigated here concerns the simultaneous design and control of structures. The structure considered is a laminated stiffened composite plate for which an optimum control system is designed by the minimization ...

Abstract: The problem of determining the statistics of the transient response of randomly inhomogeneous beams is formulated. This is based on the use of stochastic dynamic stiffness coefficients in conjunction with the fast Fourier ...

Abstract: The problem of determining the joint probability distribution of extreme values associated with a vector of stationary Gaussian random processes is considered. A solution to this problem is developed by approximating the ...

Abstract: The problem of estimation of the time-variant reliability of actively controlled structural dynamical systems under stochastic excitations is considered. Monte Carlo simulations, reinforced with Girsanov transformation–based ...

Abstract: AbstractAir lime mortars are a compatible material for the repair of ancient structures but require modifications to meet modern requirements. Since ancient times, the inclusion of pozzolans and organic admixtures in air ...
