Abstract: We evaluate the least time to failure of a linear elastic system with uncertain time‐varying input. The damage is quadratic in the velocity. The uncertainty of the load history is represented by an ellipsoidal Fourier‐bound ...

Abstract: Today's projects suffer from high uncertainty, great demand for accelerated speed, and severe scarcity of attention of the project manager. At the same time, the schedules of today's projects are expected to be more reliable ...

Abstract: A non-probabilistic, set-theoretical treatment of the buckling of shells with uncertain initial geometrical imperfections is presented. The minimum buckling load is determined as a function of the ...

Abstract: This study presents a nonprobabilistic set theoretical approach to analyzing uncertainty in vehicle vibrations arising from motion along imperfectly known terrain. The uncertainty in the substrate ...

Abstract: The redundancy of a structure refers to the extent of degradation the structure can suffer without losing some specified elements of its functionality. However, because future structural degradation is unknown during design ...

Abstract: A method is discussed for adaptive estimation of the boundary-condition influence matrix of a linear elastic system, based on modal measurements (eigenvalues and eigenvectors) and on knowledge ...

Abstract: Five different convex models are defined to represent sets of uncertain inputs. Analytical expressions are obtained for the response maxima on these convex models. We show that traditional predictions of maximum response ...
