Dataset for 3D Numerical Modeling of Compressible and Cohesive Granular Flow Impact on Narrow Obstacles

2025

Abstract

Dataset Description

This dataset accompanies the article “3D Numerical Modeling of Compressible and Cohesive Granular Flow Impact on Narrow Obstacles” published in Computational Particle Mechanics. It includes appendix material, and raw numerical time-series data with corresponding plots.

The simulations were performed using the 3D Material Point Method (MPM) with a finite-strain cohesive Cam-Clay–type constitutive model (see publication for details).

The dataset provides, for each simulation case:

Impact force (Fx):Totoal flow-wise contact force on the obstacle, computed from accumulated grid-based contact impulses. Impact pressure (σₓₓ):Material point-sampled volume-averaged Cauchy stress component in the flow direction within the impact domain. Compaction (ρ₁/ρ₀):Normalized density evolution, computed from the total Material Point mass within the sampling domain.

The quantities are provided as raw time histories for each simulation case, without filtering or post-processing. The data allow determination of peak loads, steady-state mean values, and the overall temporal evolution of force, pressure and local compaction during granular impact.

Simulation

A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of models; the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the model over time. Often, computers are used to execute the simulation. Simulation is used in many contexts, such as simulation of technology for performance tuning or optimizing, safety engineering, testing, training, education, and video games.

Data

In common usage and statistics, data (USˈdætə; UKˈdeɪtə) is a collection of discrete or continuous values that convey information, describing the quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted formally. A datum is an individual value in a collection of data. Data is usually organized into structures such as tables that provide additional context and meaning, and which may themselves be used as data in larger structures.

Force

In physics, a force is an influence that can cause an object to change its velocity, i.e., to accelerate, unless counterbalanced by other forces. The concept of force makes the everyday notion of pushing or pulling mathematically precise. Because the magnitude and direction of a force are both important, force is a vector quantity. It is measured in the SI unit of newton (N) and often represented by the symbol F.
