We're delighted to say that 2021 8th International Conference on Mechanical Engineering, Materials Science, and Civil Engineering held as a virtual conference by using Zoom just as the same as last year due to the continued impact of covid-19 pandemic. The participants are very supportive, who have joined the conference and present their papers online. On behalf of the organizing committee, we'd like to thank all the speakers and authors who have contributed to the conference. Hopefully, we'll be able to see each other and have a face-to-face conference in the near future.
On behalf of the organizing committee, we'd like to thank all the keynote speakers, oral speakers and authors. We believe we'll all survive this health crisis and get back to our normal life soon.
