Smith, who returned to training in January this year with the specific intention of making the team for Glasgow, expressed delighted at his selection.
He said: "I'm over the moon to have been selected for the Commonwealth team.
"This is something I've worked so hard towards since the end of last year and it's testament to my coach and everyone around me who have given me the support to get to this point."
Fellow Olympic medallist Whitlock beat Olympic pommel horse champion Krisztian Berki to win European gold in Sofia last month.
Whitlock said: "There's always expectation going into a major competition but I try to look at each one in the same way and perform as best I can.
"Everything comes down to getting that clean routine on the day but I'm training hard and hopeful that Team England will achieve great things in Glasgow."
The men's team also includes Olympic medallists Kristian Thomas and Sam Oldham, plus 18-year-old, five-time junior European champion Nile Wilson.
The women's artistic team is led by European Champion and double Commonwealth Games medallist Rebecca Downie, who is joined by three of the 2014 European silver medal-winning team - Claudia Fragapane, Ruby Harrold and Hannah Whelan, with Kelly Simm taking the final position.
Stephani Sherlock, Mimi-Isabella Cesar and Lynne Hutchinson will all compete in the rhythmic gymnastics competition.
