Incurrent research, aiming at the rupture problem engendered in the shooting process of acertain 5.56mm automatic rifle, the strain and stress distributions on the cartridge caseunder the action of axial pull have been analyzed. Based on the theories of elastic-plasticmechanics and contact mechanics, a mathematic and physical model of the cartridge-caseand chamber system has been set up; and based on the platform of the general softwarepackage APDL of ANSYS for finite element analysis, a parameterized model of thecartridge-case and chamber system has also been established. The method for nonlinearFEA has been adopted to analyze the stress distribution on the entire cartridge-case andchamber system, and the method of contact element has been employed to investigate thecontact stress between the cartridge case and chamber, and then the influences of frictioncoefficient and locking space on the static and dynamic stress and strain response of thecartridge case and chamber to the action of power gas have also been discussed. On thebasis of a lot of numerical tests, a kind of element Plane13, which is concentrated incoupled computation of heat and construction, has been used finally to simulate thetransient response of the cartridge-case and chamber system to the power gas. Throughloading the temporary thermal characteristics of explosive gas in the procedure of emulate, the corresponding transient thermal stress distributed on the entire system under thecombined load of transient thermal stress and transient pressure has been obtained. Owingto these comprehensive considerations, the numerical results obtained in this paperrepresent the actual situations comparatively exactly.

After we had fisht some time and catcht nothing, for when I had Fish on my Hook, I would not pull them up, that he might not see them; I said to the Moor, this will not do, our Master will not be thus serv'd, we must stand farther off: He thinking no harm agreed, and being in the head of the Boat set the Sails; and as I had the Helm I run she Boat out near a League farther, and then brought her too as if I would fish; when giving the Boy the Helm, I stept forward to where the Moor was, and making as if I stoopt for something behind him, I took him by Surprize with my Arm under his Twist, and tost him clear over-board into the Sea; he rise immediately, for he swam like a Cork, and call'd to me, begg'd to be taken in, told me he would go all over the World with me; he swam so strong after the oat that he would have reacht me very quickly, there being but little Wind; upon which I stept into the Cabbin and fetching one of the Fowling-pieces, I presented it at him, and told him, I had done him no hurt, and if he would be quiet I would do him none; but said I, you swim well enough to reach to the Shoar, and the Sea is calm, make the est of your Way to Shoar and I will do you no harm, but if you come near the Boat I'll shoot you thro' the Head; for I'm resolved to have my Liberty; so he turn'd himself about and swam for the Shoar, and I make no doubt but he reacht it with Ease, for he was an Excellent Swimmer.

我们钓了一会儿鱼，一条也没有钓到；因为即使鱼儿上钩，我也不钓上来，免得让那摩尔人看见。然后，我对他说，这样下去可不行，我们拿什么款待主人呢？我们得走远一点。他一想这样做也无妨，就同意了。他在船头，就张起了帆；我在船尾掌舵。就这样我们把船驶出了约三海里，然后就把船停下，好像又要准备捕鱼似的。我把舵交给摩尔小孩，自己向船头摩尔人站的地方走去。我弯下腰来，装作好像在他身后找什么东西似的。突然，我趁其不备，用手臂猛地在他裤裆下一撞，把他一下推入海里。这个摩尔人是个游泳高手，一下子就浮出海面。他向我呼救，求我让他上船，并说他愿追随我走遍天涯海角。他在水里像鱼，游得极快，而这时风不大，小船行驶速度很慢，眼看他很快就会赶上来。我走进船舱，拿起一支鸟枪。我把枪对准了摩尔人，并对他说我并没想伤害他，如果他不胡闹，也不会伤害他。我说：&你泅水泅得很好，你完全可以泅回岸去。现在海上风平浪静，就赶快泅回去吧。我是不会伤害你的。要是你靠近我的船，那我就打穿你的脑袋！我已决心逃跑争取自由了！&他立即转身向海岸方向游回去。我毫不怀疑，他必然能安抵海岸，因为他游泳的本领确实不赖。
