Cumulative Fatigue Damage Under stepwise Tension-Compression Loading
Rock structures are subjected to cyclic tension-compression loading due to a blasting, earthquake, traffic and injection-production in underground storage case. Therefore study the fatigue behavior of rock samples under this type of loading is required. In this study, the accumulated fatigue damage for a Green Onyx rock sample which consisted of only one mineral composition with two-step high-l...
متن کاملExpansive Soil Crack Depth under Cumulative Damage
The crack developing depth is a key problem to slope stability of the expansive soil and its project governance and the crack appears under the roles of dry-wet cycle and gradually develops. It is believed from the analysis that, because of its own cohesion, the expansive soil will have a certain amount of deformation under pulling stress but without cracks. The soil body will crack only when t...
متن کاملCumulative-Damage Reliability for Random-Independent (Normal- or Weibull-Distributed) Fatigue Stress, Random-Fixed Strength, and Deterministic Usage
To determine helicopter component retirement intervals, it is common for fatigue engineers to utilize Miner’s rule for cumulative damage. Time consuming Monte Carlo simulations are considered the state of the art method for determining reliability in the presence of load variations. However, a new set of methods employed on a recent AHS fatigue reliability round robin problem provide an indicat...
متن کاملModelling of Random Vehicle Fatigue Loads through Transformed Gaussian Processes
In this report we will present a simple way to model and simulate random fatigue loads, which are oftenly both non-stationary and non-Gaussian. The method is based on approximating the non-Gaussian process by a transformation of a Gaussian process. The procedure can be used to simulate loads as well as calculating important cycle properties of the load such as the rainnow cycle and wavelength-a...
متن کاملModelling anisotropic damage and permeability of mortar under dynamic loads
This paper deals with the development of a model for concrete subjected to dynamic loads. Shock waves are generated by Pulsed Arc Electro-hydraulic Discharges (PAED) in water and applied to mortar samples. A diphasic model (liquid water and vapour) is implemented in order to describe the electrical discharge and the propagation of shock waves in water. An anisotropic damage model is devised, wh...
