The plastoelastic solution to the problem of expansion lining in round shaft with tresca materials

摘要：

The concept of expansion-lining is put forward against the specific problems in explosive lining.A simplified mechanical model is obtained.Under the condition of material obeying Tresca yielding rule,a general solution to the maximum expansionary force of forming a shaft with definite inner diameter in the lining materials,the solution result indicates that maximum expansionary pressure have relationship with the lining material,yield stress,elastic ratio and Poisso ratio of soil body.The more lining materials yield stress and soils yield stress,the more maximum expansionary pressure.
