In the tensile test for a nanocomposite sample, if the sample width decreases (thickness is constant), what does the stress-strain curve change?

Given that the stress is equal to the force divided by the area(width*thickness), what change does the reduction in sample width make to the stress-strain curve? Does stress change occur...

I would like to draw your attention to the reinitialization procedure discussed in section 3.2. This procedure is crucial to obtain a high fidelity rendering of the boundary.

I hope that this is useful in resolving your question.
