of the questions to be solved in order to avoid errors in the characterization of biological agents, being necessary to identify and detach the frequency shifts coming from the added mass and the stiffness changes.[10]
When working in the dynamic mode, the resolution of the system, Df, is determined by the quality factor, Q, following the expression △f=f/Q. The quality factor quantifies the
of atoms slip past each other easily, absorbing energy and allowing dislocations to move, making deformation permanent.
Grain boundaries represent weak spots
Also called Metallic glasses or glassy metals
Cooled faster than atoms can rearrange into a crystal.
Dislocation movement obstructed so absorbs less energy and rebounds elastically to its initial shape.
Resistant to corrosion and
of the plate로서, 아래와 같이 정의된다.
(E: Young's modulus , t: thickness of plate, :Poisson's ratio)
FEM을 ‘요소'를 나누어 계산하는 방법이다. 계산을 위해서 FEM을 시행하는 개인들은 주어진 Object를 Beam, Plate, 3D-Structure 등으로 나름의 idealize를 한다. 때문에 무엇으로 요소를 idealize 했느냐에 따라서 그 요소를
2.4. Bonjean Curve
많은 학생들이 Bonjean Curve 에 대해 답을 하지 못하였다고 하셨다. 우리 조원들도 이 문제에 대해 거의 답을 하지 못하였다고 했다. Bonjean Curve는 부력의 개념이다.

임의의 수선에서 횡단면의 면적은 Simpson's 1st Rule 같은 방법으로 구할 수 있고 이를 수선변화에 따른 곡
Seeks growth: decentralized, flexible and elastic structure, high R&D abilities, creative, risk taking. Give high value to innovaton
Seeks efficiency: highly centralized structure, and strict cost management
Balance in growth and efficiency: being creative to improve to production process in a stable product line.
No clear strategy. Changes the characteristics of the organizational
