Product Design and Development

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 Suraj D Dhomase

Hello All, Connection modelling and analysis in any type of assembly is very important and difficult stage. For modelling different type of connection such as Bolts, Rivets, Welding and adhesives. Today we will discuss welding modelling. As per modelling approach welding can be modeled and analysed with the help of 1D, 2D and 3D elements. For detailed representation of welding we modeled it into 3D (Hex) Elements. ELFORM-01, Mat_100_spot weld. *Contact_shell_edge_to_surface For different type of materials in LS_DYNA we can model failure of spot weld. Thank You. Suraj D Dhomase
