Aim\ By means of stationary perfect incompressible fluid-dynamics theory
the distortion process of cuneiform liner during the explosion of linetype Mohaupt charge is analyzed. The application of cuneiform liner aspects of engineering technology is studied. Methods\ Theoretical analysis and experiments were combined. Results The penetration quality of SFF group formed from cuneiform liner is powerful. Conclusion\ Cuneiform liner is of important application value on the engineering demolition and engineering protection technologies. It also has significant reference value and guidance meaning for the design of SFF.
