Presentation Title: Analysis for Pull-in Voltage Variations of Fixed-Fixed Beam with Elastic Deformation in Current Input

Reflection

I feel honored to have participated in the 2015 ASEM International Seminar, where scholars from around the world gathered to promote academic exchange and enhance international perspectives. The conference was a great challenge for me, especially listening to the different accents of English spoken by people from different countries, as it was my first time abroad. However, it was also a valuable experience that reinforced the importance of learning international languages and taking advantage of opportunities to improve English proficiency.

During the conference, I presented a study on how the deformation of fixed-fixed beams under current input can cause changes in their adsorption voltage. After my 10-15 minute presentation, several scholars posed the following questions:

Q1. What is the purpose of this research?

Q2. Which part of the component does the maximum deformation refer to?

Q3. Does the initial stress affecting the component due to thermal stress considered?

Q4. Is the electrostatic distribution uniform on the component?

In answering these questions, I used simple English sentences to express what I wanted to convey, but I was nervous and somewhat hesitant, which resulted in a less-than-ideal performance. I think this is because my preparation was not sufficient, and there were many blind spots that I had not considered. However, the questions posed by other scholars during the seminar helped me to break through my own limitations and learn about things that I had not previously considered. By exchanging ideas and understanding the perspectives of others, I was inspired to work harder and push myself to improve.

Furthermore, after the seminar, Professor Wang from National Cheng Kung University expressed an interest in my research topic and raised additional points of discussion regarding the effects of electrostatic forces on the distribution of charges in various geometric positions of the component. This was an interesting and inspiring direction for me to consider, and I am deeply convinced that such academic exchanges are beneficial for students to not only learn about their shortcomings but also to enhance their research and critical thinking skills. Overall, I gained a lot from this conference.

Listening Session 1

Towards improving shell and beam finite elements

The author utilizes two types of node shell elements to further analyze biological and nanostructures in finite element simulations, which can effectively achieve convergence regardless of mechanical behaviors such as distortion, bending, or warping in the structure.

Listening Session 2

Investigation of the fatigue damage in a half through steel Lohse bridge 

This presentation focuses on simulating bridges under various forms of loads and observing the resulting fatigue damage. The speaker mentions dead load and live load, which refer to fixed loads that do not vary in size, position, or direction.

Listening Session 3

Experimental Construction of a Temporary Church in Reinforced Ice

The presentation is given by a Finnish professor who discusses the process of creating an ice house during the course of his research project. In addition to having a certain structural composition, the ice house must also be constructed in harsh weather conditions in order to be completed. The photos of the experimental results impressed everyone.

Listening Session 4

Effect of white layer on the distribution of stresses and strains in thin annular discs subject to internal pressure

The author used mathematical formulas to analyze the stress and strain distribution of a white layer in a thin disk under internal pressure. Because thin disks are subject to residual stress during manufacturing, this analysis method can effectively determine the potential outcomes of the component.

Listening Session 5

Effect of Pressure-Dependence of the Yield Criterion on Residual Stresses in Rotating Annular Discs

The author of this paper proposes a yield criterion for rotating disks, which, combined with equations, can determine the stress distribution under rotation at zero angular velocity and the elastic-plastic boundary.
