Summary
This study introduces a numerical method to quantify uncertainties in wave-structure interaction (WSI). The approach combines Smoothed Particle Hydrodynamics (SPH) for wave modeling with Finite Element Method (FEM) for structural analysis, enabling probabilistic response prediction.
Area of Science:
- Fluid mechanics
- Structural engineering
- Computational science
Background:
- Wave-structure interaction (WSI) is crucial for offshore and near-shore structures.
- Existing numerical models often neglect uncertainties in wave and structural parameters.
- Deterministic approaches limit the analysis of complex WSI phenomena.
Purpose of the Study:
- To develop a numerical framework for uncertainty quantification in WSI.
- To couple Smoothed Particle Hydrodynamics (SPH) with Finite Element Method (FEM) for coupled analysis.
- To predict the probabilistic forces and responses of structures under various wave conditions.
Main Methods:
- One-way coupling of SPH for wave hydrodynamics and FEM for structural response.
- Implementation of uncertainty quantification within the coupled SPH-FEM framework.
- Validation using the Tokyo wave flume geometry and comparison with literature data.
Main Results:
- Successful quantification of uncertainties in wave-structure interaction forces.
- Demonstration of probabilistic structural responses under breaking and non-breaking waves.
- The developed model shows potential for future surrogate modeling in WSI.
Conclusions:
- The proposed numerical framework effectively quantifies uncertainties in WSI.
- This method provides a robust approach for predicting the probabilistic behavior of structures.
- The study highlights the importance of considering uncertainties in the design of marine structures.

Werner Heisenberg considered the limits of how accurately one can measure properties of an electron or other microscopic particles. He determined that there is a fundamental limit to how accurately one can measure both a particle’s position and its momentum simultaneously. The more accurate the measurement of the momentum of a particle is known, the less accurate the position at that time is known and vice versa. This is what is now called the Heisenberg uncertainty principle. He...

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

In analytical chemistry, we often perform repetitive measurements to detect and minimize inaccuracies caused by both determinate and indeterminate errors. Despite the cares we take, the presence of random errors means that repeated measurements almost never have exactly the same magnitude. The collective difference between these measurements - observed values - and the estimated or expected value is called uncertainty. Uncertainty is conventionally written after the estimated or expected value.

All the digits in a measurement, including the uncertain last digit, are called significant figures or significant digits. Note that zero may be a measured value; for example, if a scale that shows weight to the nearest pound reads “140,” then the 1 (hundreds), 4 (tens), and 0 (ones) are all significant (measured) values.

00:54Uncertainty: Confidence Intervals

The confidence interval is the range of values around the mean that contains the true mean. It is expressed as a probability percentage. The interpretation of a 95% confidence interval, for instance, is that the statistician is 95% confident that the true mean falls within the interval. The upper and lower limits of this range are known as confidence limits. The confidence limits for the true mean are estimated from the sample's mean, the standard deviation, and the statistical factor...

The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.
