A STensor followed by bracket with indices string can be used in computation:
In[2]:=
T=
["T",{0,2},{x,y},Array[&,{2,2}]];S=
["S",{0,1},{x,y},Array[&,{2}]];

Out[3]=

Get its components:
In[4]:=
t
2
Out[4]//MatrixForm=
2 S 1 1 2 T 1,1 | S 1 S 2 1 2 T 1,2 |
S 1 S 2 1 2 T 2,1 | 2 S 2 1 2 T 2,2 |
The symbol of the result will be the expression:
In[5]:=
t
2
Out[5]=
(t/2) T+S S
