It does not seems to be wrong.
Run the following code and see if it works fine:
x = linspace(0,10);
y = sin(x);
plot(x,y,'-o','MarkerIndices',1:5:length(y))

The MarkerIndices name-value pair is relatively new.
If you do not have it, it is straightforward to do that with a second plot call:
figure
plot(t_010_tbc_r_002,stress_010_01,'-b')
hold on
plot(t_010_tbc_r_002(idx),stress_010_01(idx),'ob')
hold off
Experiment to get different results.

Thank you very much Star Strider. It works.
figure
plot(t_010_tbc_r_002,stress_010_01,'-b')
hold on
plot(t_010_tbc_r_002(1:10:length(t_010_tbc_r_002)),stress_010_01(1:10:length(stress_010_01)),'ob')
hold off

The marker indices functionality was introduced in version R2106b. If you have an older version, then you'll get an error.
You can find a suggested work-around in this question.
