TENSILE TEST SIMULATION

TENSILE TEST SIMULATION

Introduction:

This specimen is nickel paint coating made up of three layers each of three different grain sizes. We need to test the material strength by doing virtual tensile testing.

Virtual Tensile Test and material non-Linearity

Challenges:

Elasto-plastic material with Vonmises hardening and associated plastic flow. The true stress-strain curve was taken from experimental data.

Scope of Work:

The tensile test specimen was analysed for four different case studies. case1: tensile test on specimen with 21nm grain size nickel material, case2: tensile test on specimen with 42nm grain size nickel material, case3: tensile test on specimen with 195nm grain size nickel material, case4: tensile test on specimen bonded with the above three cases of nickel material.

Engineering Solution:

After doing virtual testing, the results were matched with practical tests with 6% difference.
