Aims
The general aim of the project is
to develop further understanding of the deformation and overall response of
construction materials when subjected to ballistic impact, by taking advantage
of numerical finite element modelling. Before the end of the project there are
several goals that our team aims to achieve.
The initial priority is to become proficient with the Abaqus software and to be able to create models that can match experimental results and analytical predictions accurately. Understanding the theory behind the model is essential. Producing final results which present information new to the field of terminal ballistics. Those can be models of the response of materials that have not been researched so far. Finally a very important skill that our team will aim to gain from this project is the ability to communicate information according to the highest academic standards. |
Objectives
1. To
conduct a literature review that will be used to get an in depth understanding
of the project. The literature review will also identify trustworthy
experimental results that can be used for comparison with the initial model.
2. To develop an initial model of a terminal ballistics scenario that can easily be compared to experimental results. The use of this comparison is to draw conclusions about the applicability of this type of computational modelling to the problem This will identify the factors which the model fails to account for. This model will have basic geometry that is comparable to a selected set of experimental results. The agreement with experimental results will be achieved by the implementation of complex material models such as the Johnson-Cook plasticity model. 3. Once the model has been validated against experimental results, further conformity can be achieved by comparison to analytical models that are already available. 4. To use the understanding of the limitations of the basic model to explore scenarios for which there is no experimental research available. These scenarios will be identified at a later stage in the project after consulting with the project supervisor. At this stage the team that will decide upon going into two different research directions. 5. To produce a written Thesis document that communicates the research that has been done in accordance with academic standards. The document should present the information in a clear and organized way. |
