Is it allowed to submit accepted and published journal articles in Elsevier, to arXiv?

As arXiv allows submitting research articles which helps in increasing its visibility. I was wondering if it is alright to submit accepted and published journal articles in Elsevier (Expert Systems with Applications, International Journal of Medical Informatics) to arXiv?
