Loading spectrum for highway bridges and damage criteria for cumulative loading.

2009
Bridges are presently designed to withstand the bending moments and shear forces produced by a standard design truck such as AASHO H2O-S16. However, bridges are subjected to a large number of loads of different magnitude randomly ordered with respect to time.

Fatigue Crack Growth Behavior under Spectrum Loading

2009
The purpose of this study is to investigate experimentally the fatigue crack growth behavior under typical service loading spectrum recorded from military P-3 cargo airplane. The material is 2324 — T39 Al alloy widely used in the aircraft industry. Experiments were conducted using the full spectrum and modified versions of it such as only ‘positive ...

Spectrum Load Balancing for Flexible Spectrum Usage in Local Area Deployment Scenario

2008
In this paper we propose a non-contention based mechanism for allocation of the spectral resources by several interfering Home e-NodeBs (HeNBs) deployed by the same or different operators, potentially in random manner in a given geographical area.

Crack growth retardation under aircraft spectrum loads

Engineering Fracture Mechanics, 1973
Abstract In the past, the prediction of the fatigue life of a part was often compared with Miner's rule (Σn/N = 1) wherein damage was computed by a linear accumulation of growth under individual loads. The difference between the predicted and observed damage for variable amplitude tests showed up as either retarded or accelerated fatigue life ...
