Typical response of a truss member (called "strut"): (a) Compressive stress-strain; (b-d) 2 types of buckling

From the same paper as the previous image.

Figure 11. (a) Compressive stress–strain response of the E-glass struts; (b) and (c) are examples of compressive fiber microbuckling and (d) Euler elastic buckling failure of E-glass struts loaded parallel to the weft tow direction with thickness to length ratios of (b) 0.18 (5.25 mm), (c) 0.12 (3.5 mm), and (d) 0.07 (1.75 mm).
