Hu Haichang
Hu Haichang (; April 25, 1928 – February 21, 2011) was a Chinese mechanical and aerospace engineer. He was in charge of the early phase development for the Dong Fang Hong I, China's first artificial satellite. Hu was an academician of the Chinese Academy of Sciences. Biography Hu was born in Hangzhou, Zhejiang Province in April 1928. Hu graduated from the Department of Civil Engineering, Zhejiang University in Hangzhou, and his academic advisor was Chien Wei-zang. After graduation, Hu joined the Institute of Mechanics of the Chinese Academy of Sciences (CAS) in Beijing, which was mainly founded by Tsien Hsue-shen in 1950s. From 1968 until retired, Hu worked for the CAS Department of Spacecraft System Design.

Academic Staff Of Peking University
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Engineers From Zhejiang
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professional pr ...

Continuum Mechanics
Continuum mechanics is a branch of mechanics that deals with the mechanical behavior of materials modeled as a continuous mass rather than as discrete particles. The French mathematician Augustin-Louis Cauchy was the first to formulate such models in the 19th century. Explanation A continuum model assumes that the substance of the object fills the space it occupies. Modeling objects in this way ignores the fact that matter is made of atoms, and so is not continuous; however, on length scales much greater than that of inter-atomic distances, such models are highly accurate. These models can be used to derive differential equations that describe the behavior of such objects using physical laws, such as mass conservation, momentum conservation, and energy conservation, and some information about the material is provided by constitutive relationships. Continuum mechanics deals with the physical properties of solids and fluids which are independent of any particular coordinate sy ...

Hu–Washizu Principle
In continuum mechanics, and in particular in finite element analysis, the Hu–Washizu principle is a variational principle which says that the action :\int_ \left \frac \varepsilon^T C \varepsilon - \sigma^T \varepsilon + \sigma^T (\nabla u) - \bar^T u \rightdV - \int_ \bar^T u\ dS is stationary, where C is the elastic stiffness tensor. The Hu–Washizu principle is used to develop mixed finite element method The finite element method (FEM) is a popular method for numerically solving differential equations arising in engineering and mathematical modeling. Typical problem areas of interest include the traditional fields of structural analysis, heat ...s. The principle is named after Hu Haichang and Kyūichirō Washizu. References Further reading * K.
