Abstract: PURPOSE: A process analyzing method with a computer and a computer-readable recording medium including a program for executing the method are provided to sufficiently reduce a calculation quantity and a calculation time when analyzing a process having plastic deformation locally generated in a material. CONSTITUTION: Formulas to be calculated for process analysis are arranged(S120). The arranged formulas are analyzed by using an FEA(Finite Element Analysis) method(S130). A displacement field is updated according to the analysis result and the existence of a plastic area in a material is determined according to the result(S150). If there is not the plastic area, analysis is performed. If there if the plastic area, the arranged formulas are rearranged as a stiffness matrix to be composed of a partial matrix of an elastic area and a partial matrix of the plastic area and the rearranged formulas are analyzed through the FEA method(S170).

Abstract: PURPOSE: The sructure can be simplified, the electrical energy consumption can be reduced. It can manufacture with miniature and light weight, it is contolled minute drive. CONSTITUTION: A fluid propulsion device comprises a propeller body(100), a pressure unit(200), and a guide member(300). The presser unit installs to the propeller body. The presser unit pressurizes the propeller body so that 'the fluid flowing in inside the propeller body be compulsorily flown. The guide member is offered inside the propeller body. The propeller body is pressurized with the presser unit. In order to the fluid which is compulsorily flown in the inside of the screw main body be collected in one side and it is exhausted the flow path of the fluid is defined.
