UnderWater Shock Analysis

hi all,

   thanks lot, actually how to solve nonlinear buckling analysis?

1.what is the adavantage of nonlinear analysis,will u get new critical load or same value of linear buckling load?

2.one of the imechanica member suggested the follwing code,i done using tha t code but what ever im giving time value same value getting after converging my solution.

新技术无力测试损检测残余应





导言



内部压力，也应视为如下： 1 ）业务株提到负荷的材料是受计算2 ）残余应力引起的材料热处理或强调造成的焊接，锻造，铸造等方面的新技术能够衡量载荷和残余应力的平衡表面的材料，并在一个比较大的音量，有时甚至相同的大小作为整个结构。这强调的是部分金属的弹性场和有三个轴的空间取向。





描述



 弹性振荡（也称为振动）的弹性材料组成的小学群众轮流走动各自的平衡位置;这些运动造成的潜力转化成能源的动能。这种现象发生，由于反应（弹性部队） ，上述群众生产反对弹性运动;这些反应是成正比根据胡克定律，以相同的动作。弹性波的传播产生按照固定的速度，取决于如何迅速元素群众开始振荡。

Dear all

 I am trying to model damage at the interface of Dentine and enamel. AS the property of dentine material crack grown in the area of Dentine Enamel Junction(DEJ), when comes to dentine region,it start arresting due to prescence of collagen and mineral fibers in the dentine composite. I am trying to simulate that crack arresting property by modelling the DEJ region with user element facility in abaqus with crack arresting or crack healing capabilities.

Can some body help me in this regard ?

I'm working in a iterative method with piezoelectric composites. During the implementation (in MATLAB) I work with the piezolectric components in a single matrix, reduced to a vector by the Hill algebra. However, I'm having problems because of the different orders of the components values. I know there is a way to normalize all the values, but it can't be by dividing the whole matrix by the same number, so, if anybody can help me I will appreceite it. You answer here or write me to naecita [at] gmail.com

Hi every body,

I write a program which draws the shear and bending moment diagrams of a simple beam on matlab.inputs are loads(couples,forces,constant distributed forces and and linear distributed forces) and outputs are shear diagram and bending moment diagram. I want to add free body diagram of the beam too,but i don't know how can I do it,Can anybody help me to solve this problem?

tnx
