Impact of the bottle full of water with the ground in the Abaqus software

Project Overview

This tutorial focuses on the impact of a bottle full of water with the ground using the Abaqus software. The main objective is to investigate the behavior of the bottle and the water during the impact process.

The simulation includes the deformation of the bottle, the movement and sloshing of the water, the separation of the bottle cap, and the water flow during and after the impact.

Problem Description

In this example, a water-filled bottle is dropped from a height of 300 mm. As a result, the initial velocity of the bottle at the moment of impact is 2444 mm/s.

The bottle impacts the ground at an angle of 20 degrees. The weight of the bottle, bottle cap, and water is applied using a gravity load.

Bottle Modeling

The bottle is made of high-density polyethylene (HDPE). The elastic, plastic, and damage properties of the polyethylene are defined in Abaqus to simulate the deformation and failure behavior of the bottle during impact.

The bottle cap is also included in the model. During the impact, the bottle cap separates from the bottle and moves freely.

Eulerian Modeling of Water

The water is modeled using the Eulerian method. This approach allows the water to undergo large movement and deformation during the impact.

The interaction between the deformable bottle and the Eulerian water is investigated throughout the analysis. The simulation also captures the sloshing of water inside the bottle.

Impact and Bottle Deformation

When the bottle hits the ground, the bottle undergoes deformation while the bottle cap separates from the bottle and moves freely.

At the same time, the water inside the bottle moves and undergoes significant deformation due to the impact.

Water Sloshing and Flow

The impact causes significant movement and sloshing of the water inside the bottle. As the analysis progresses, water flows out of the bottle.

At the end of the analysis, a considerable amount of water has gushed out of the bottle.

It is important to note that water can flow inside the Eulerian part. If water exits the Eulerian domain for any reason, it is removed from the computational domain and its deformation can no longer be observed.

Reaction Force

The reaction force of the ground is also obtained from the Abaqus analysis. The reaction force diagram can be used to investigate the force transmitted to the ground during the impact.
