两种常用应变硬化模型 如图所示,随动硬化模型(Kinematic hardening)假设弹性范围(初始屈服应力的两倍)保持不变。弹性范围的中心沿着虚线穿过原点,平行于应变硬化线。 在各向同性硬化模型(Isotropic hardening)中,假定材料因拉伸后屈服应力增加,而压缩时的屈服应力同样增加,即反向加载的屈服应力大小等于先前屈服应力的大小。
worker.working(); } //为半透明模式做的拓展 public void heating(){} } 具体的技能类1: public class Hardening extends Skill { public Hardening(Worker worker) { super(worker); } @Override Worker worker1 = new Smith("李铁蛋",18); Worker worker2 = new Hardening(worker1); 半透明的装饰模式: 当发现工人接口并不能满足所有的要求的时候 本例中,装饰者类就是技能类,我们为淬火技能类添加加热方法 Worker worker = new Smith("李狗蛋",18); Hardening smith = new Hardening(worker); smith.heating(); 半透明的装饰者模式是介于装饰者模式跟适配器模式中的,适配器模式的思路是改变接口,也可以通过改写或新增方法实现

3、JIT Hardening JIT Hardening是防止对JIT引擎本身的滥用的机制。JIT引擎通常在可预测的地址空间中放置可执行代码,这无疑给攻击者提供了可乘之机。 JIT Hardening常用技术包括:代码库队列随机化、指令库队列随机化、常量合并、内存页面保护、资源限制等。 4、数据执行保护(DEP) DEP是一种阻止数据页执行代码的机制。 图3 Chrome和IE沙箱机制对部分行为的限制情况 总结 浏览器发展至今,已经拥有比较成熟的安全机制,主要包括沙箱机制、JIT Hardening、地址空间布局随机化、数据执行保护、缓冲区安全检查
