ABSTRACT

This study investigates the ballistic performance of aluminium alloy Al7075-T6 and magnesium alloy AZ31B served as the intermediate layer in triple-layered metal-laminate panel using computational method. Aluminium and magnesium alloys offer a considerably potential for reducing the weight of an armoured vehicle body due to low densities and high energy absorption capabilities. The poor ballistic performance of these materials can
be improved by layering with the high strength steel. A commercial explicit finite element code was implemented to develop triple-layered panels impacted by a 7.62 mm armour piercing projectile at velocity range of 900 to 950 m/s. Two models were constructed where aluminium alloy and magnesium alloy served as intermediate layer in the first model and the second model respectively. The ballistic performance of each model in terms of ballistic limit velocity and depth of penetration was evaluated. Considering the 25% existing armour vehicle weight reduction, it was found that magnesium alloy has equivalent ballistic limit to that of aluminium alloy which is at 1020 m/s. At the standard projectile velocity, aluminium stopped the projectile at 24 mm depth and magnesium stopped at 25 mm. Thus, lightweight materials can be suitable combinations for designing lighter
armoured vehicle panel without neglecting its ballistic performance.

Keywords: Armour piercing projectile; ballistic limit; depth of penetration; finite element; lightweight material.

Mahidol EcoLab meets with CHAROEN POKPHAND GROUP CO., LTD.

On 10 August 2017, Asst. Prof. Dr. Trakarn Prapaspongsa, head of Mahidol EcoLab (Eco-Efficient Engineering Research Lab along with her research team from International Master Program in Environmental and Water Resources Engineering, Department of Civil and Environmental Engineering, Faculty of Engineering, Mahidol University met with Ms. Jeeranee Janrungauthai – Assistant Director, Sustainability Development and Governance Audit, Sustainability, Good Governance and Corporate Communication Office (SGC) of CHAROEN POKPHAND GROUP CO., LTD. at C.P. Tower 2 Building in order to discuss future research collaborations. The meeting aimed at presenting the overall framework of the two projects. Firstly, “Development and Application of Life Cycle Impact Assessment Method for Supporting Sustainable Food Innopolis and Bioenergy Industry in Thailand” – a sub-project under “Network for Research and Innovation for Trade and Production of Sustainable Food and Bioenergy” project – funded by National Science and Technology Development Agency (NSTDA Research Chair Grant 2016) was presented. Secondly, “Environmental Footprints of Food Supply Chains towards Sustainable Consumption and Circular Economy in the UK and Thailand” – a collaborative project between Mahidol University in Thailand and Liverpool John Moores University in the UK was demonstrated and discussed. In the meeting, various collaboration platforms were proposed such as being users of the future research results, participating in the research as co-researcher/data provider/funding institution, etc.

The “RESET – REliability and Safety Engineering and Technology for large maritime engineering systems” project (with total funding of €1,417,500 from EU) is collaborative research among 9 universities from 7 countries – Liverpool John Moores University (UK), Aalto University (Aalto-Korkeakoulusäätiö; Finland), Instituto Superior Tecnico, Universidade of Lisbon (Portugal), Leibniz University Hannover (Germany), University of Plymouth (UK), Mahidol University (Thailand), Universiti Kebangsaan Malaysia (National University of Malaysia; Malaysia), Universiti Teknologi Malaysia (Malaysia), and Wuhan University of Technology (China).

 

The RESET project leader at Mahidol University is Asst. Prof. Dr. Wonsiri Punurai and the team members include Asst. Prof. Dr. Trakarn Prapaspongsa, Asst. Prof.Dr. Yasothorn Sapsathiarn, and Asst. Prof. Dr. Teraphan Ornthammarath from Department of Civil and Environmental Engineering, Faculty of Engineering. Under this project, there will be short- and long-term visits of professors and researchers from all partner universities in order to carry out research and organize seminars as well as international conferences from 2017 to 2021.

 

In addition, on 20th July 2017, Professor Jin Wang from Liverpool John Moores University, UK, who is the principal coordinator of this program give a special seminar organised by Department of Civil and Environmental Engineering, Faculty of Engineering, Mahidol University. The topic is ”A Risk-Based Approach in Design and Operation of Large Maritime Engineering Systems under Uncertainties”

 

Staffs from Mahidol University will have more opportunities from this collaboration and also interesting research outcomes from the RESET project funded by the European Union’s Horizon 2020 research and innovation programme throughout these four years.

In addition to regular Open House visits in November every year, we offer expanded programming during school break in the summer. On 11 August 2017, around 60 students from Kanjanapisek Wittayalai Nakhon Pathom School, a local high school in Salaya, visited Department of Civil and Environmental Engineering Laboratory. Some of our activities including Stress-Strain Test, Shake Table Test, Soil Liquefaction Test, and Environmental Engineering Lab Test. These Open Houses give prospective students and their families a chance to get to know the Mahidol University’s academic community, our campus, and our home in Salaya. Our faculties offered students a hand on experience on science for their future career. Our faculties who led this program were Asst. Prof. Dr. Praveen Chompreda, Asst. Prof. Dr. Teraphan Ornthammarath, and Dr. Nawat Surinkul with Master students as supporting staffs.
