The study of fixture and FMD in force limited vibration tests;

Taking the vibration test in the vertical direction of a satellite central tube as an example, the test platform to implement the force limited vibration test is presented, including the fixture and FMD, force signal acquisition and processing, force transducer calibrating.

By Force limited control vibration test attempting,this paper compares the result of force limited method with acceleration controlled method,and indicates the control precision of force limited method is higher.

FEM design of cruciform biaxial tensile specimen based on limit stress analysis;

A new method for establishing forming limit stress diagram of sheet metals;

The abrasion fatigue limit stress is about(3.

Effect of media flow velocity on limit pressure of pipes during in-service welding;

Finite element simulation of limit pressure pipeline with cracks using critical crack-tip-opening-angle;

Based on the numerical results,the remaining strength factor of the pipe can be obtained and limit pressure can be predicted.

Mobility analysis and calculation the in-situ stress changes caused by waterflooding are used to define whether the formation is fractured, and to define the reasonable pressure limit of high pressure waterflooding.

A new method to monitor and diagnose steel cord belt splice breaking and tension exceeding limit was presented based on measurement and analysis of F L(tension length) curves of steel cord belt splices.
