Determining plasticity parameters of AISI 4130 Steel

Determining plasticity parameters of AISI 4130 Steel

Determining plasticity parameters of AISI 4130 Steel

(OP)
Hi, I hope that someone can help me.

I am currently investigating the crash deformation of a tubular space frame chassis on Ansys (Explicit Dynamics)

Ansys has a number of preset Explicit Dynamic Materials that define the characteristics required to help model the material requirements for use with a high impact collision. Unfortunately however, is does not feature 4130, the closest i found was 4340 (which is a much stronger material.)

Does anyone on here have or could point me in the direction of any information that could help me defining the plasticity characteristics of the material (ideally johnson cook strength data) for an 4130 stainless steel.

Thank you

Ryan

RE: Determining plasticity parameters of AISI 4130 Steel

you need to look at the aircraft industry, SAE 4130 is a low alloy Chrome moly steel, not stainless, it is extensively used in welded aircraft steel tube fuselages, look there for analysis.

eBook - Mastering Tolerances for Machined Parts
When making CNC machined parts, mastering tolerances can be challenging. Are general tolerances good enough? When does it make sense to call out for tighter tolerances? Do you need a better understanding of fits, datums, or GD&T? Learn about these topics and more in Xometry's new e-book. Download Now
eBook – How to Choose the Correct Corrosion Testing Method
When designing a metal component, engineers have to consider how susceptible certain alloys are to corrosion in the final product’s operating environment. In a recent study by NACE (National Association of Corrosion Engineers), it was estimated that the direct and indirect costs of corrosion in the United States is approximately 6.2% of the GDP. In 2016, that cost exceeded $1 trillion dollars for the first time. Download Now
