Correction to: Applied Composite Materials

  https://doi.org/10.1007/s10443-018-9693-1

The original version of this article unfortunately contains mistakes. Below are the corrections:

1) In Equation 1, a “less-than or equal to (≤)” sign was captured in the third line instead of the correct “less than sign (<)”. The correct equation is shown below:
$$ P=\Big\{{\displaystyle \begin{array}{ccc}\frac{\delta }{\delta_1}{P}_{\mathrm{d}}& & \left(0\le \delta \le {\delta}_1\right)\\ {}\frac{\delta_2-\delta }{\delta_2-{\delta}_1}{P}_{\mathrm{d}}+\frac{\delta -{\delta}_1}{\delta_2-{\delta}_1}{P}_{\mathrm{f}}& & \left({\delta}_1\le \delta \le {\delta}_2\right)\\ {}{P}_{\mathrm{f}}+\frac{\delta_2-\delta }{h-{\delta}_2}{P}_{\mathrm{f}}& & \left({\delta}_2<\delta \le h\right)\end{array}} $$
(1)

2) In Equation 9, a “minus (-)” sign is missing in the second line and a “less-than or equal to (≤)” sign was captured in the third line instead of the correct “less than sign (<)”. The correct equation is shown below:

$$ {\tau}_s=\Big\{{\displaystyle \begin{array}{ccc}\frac{\tau_{\mathrm{d}}}{\delta_1}\delta & & \left(0\le \delta \le {\delta}_1\right)\\ {}\frac{\delta_{\mathrm{f}}{\tau}_{\mathrm{d}}-{\delta}_{\mathrm{d}}{\tau}_{\mathrm{f}}}{\delta_2-{\delta}_1}-\frac{\tau_{\mathrm{d}}-{\tau}_{\mathrm{f}}}{\delta_2-{\delta}_1}\delta & & \left({\delta}_1\le \delta \le {\delta}_2\right)\\ {}\frac{h-\delta }{h-{\delta}_2}{\tau}_{\mathrm{f}}& & \left({\delta}_2<\delta \le h\right)\end{array}} $$
3) Figures 6, 11, and 13 were not updated during the modification stage. The correct figures are now shown below.
