摘要: Abstract The Technical Committee 4, “Polymers, Polymer Composites and Adhesives”, of the European Structural Integrity Society (ESIS TC4) developed a draft protocol based on load separation criterion to determine two fracture parameters (an initiation parameter, JI,lim, crack growth ms) without need measure (Δa). This is especially beneficial, since measurement Δa prone errors. testing scheme displays promising results, as shown in round-robin exercise. To further push this scheme, it necessary verify specimen size scaling possibility. Hence, work, single edge notched bending (SE(B)) specimens with different sizes, but geometrically similar, were manufactured. ESIS TC4 was successfully applied data JI,lim ms obtained. observed effect aforementioned presented discussed.
