Material Testing and Validation in CAE



Hello All,
Crash worthiness is defined as a ability of structure to withstand a crash energy and safeguard the occupant.For this i simulated one small crush-Box.For accurate material modelling material testing and validation is very important step in CAE. After accurate material selection and validation in CAE we can simulate our whole product.The energy absorb by this box is shown n figure.
Crush box simulation is Quasi-static type of analysis. For physical testing of material UTM is used.For material testing quasi static conditions are used.
For crash worthiness material which depends on strain rate different type of strain rate must considered. Every material is strain rate dependent. The term material high strain sensitivity must consider for crash scenario.

Thank You

LS-DYNA Revolute Joint (Hinged Joint)

Hello, Today we are going to discuss about Mechanical joints with the help of Finite Element Analysis. There are 4 types of mechanical joints, 1. Revolute Joint 2. Cylindrical Joint 3 Universal Joint 4.Spherical Joint Revolute Joint A  revolute joint  (also called pin  joint  or hinge  joint ) is a one-degree-of-freedom kinematic pair used in mechanisms.  Revolute joints  provide single-axis rotation function used in many places such as door hinges, folding mechanisms, and other uni-axial rotation devices. In automobile there are various locations revolure joint used. Some subsystem are, 1. Seating System 2. Stearing column 3. Wheel Assembly etc. Simulation of Revolute joint in  LS-Dyna need predecessor like Hypermesh.    The simulation of Revolute Joint is as shown.The energy graph given Below. The loading condition as, 1. Constrain hinged one bar, 2. Model under Gravity 3. Revolute Joint defini...

Hello All, This is my first blog I am writing. Product design and development is very complex process in the present era. Product design and development are mainly two phases in industry. The asset of company is its product. So lets talk about it. Product Design Any kind of need for something leads to product concepts. Need is the most basic thing in concept design phase. Survey of market leads to identification of need of customer. After product concept you are diverting to actual start of product design. In this process you will finalize shape, size , appearance , specification and many more. This all are finalized on the basis of market survey. Now this product are converted into 3 D data that we called CAD. But much more people are confused in design and CAD. So make sure that you aware of it. Product Development This is next phase of product.3D model is then going to CAE department for analysis purpose. CAE is best technique for accelerating your product development cycl...
