“…The strength (static and fatigue) performance of laminated unidirectional constructions is discussed in refs. [6][7][8][9][10][11], which considers their failure morphology, depending on the fiber orientations, stacking sequences, and forms of their holes. The allowable loads for laminated composites are determined/defined by various parameters, such as the initial loads when the failure load occurs.…”

The static and fatigue analysis of plates made of 2D woven roving composites with holes is conducted. The parametrization of convex holes is proposed. The experimental results of the specimens without holes and with different shapes of notches are discussed. The experiments and the appropriate procedures are carried out with the aid of ASTM codes. The fatigue behavior is considered with the use of the low cycle fatigue method. The analysis is supplemented by numerical finite element modeling. The present work is an extension of the results discussed in the literature. The damage of plates with holes subjected to tension always occurs at the tip of the holes, i.e., (x = a, b = 0), both for static and fatigue failure. The originality and the novelty of this approach are described by the failure’s dependence on two parameters: n and the ratio of the a/b ratio characterizing the hole geometry. The fuzzy approach is employed to reduce the amount of experimental data.

“…In addition, considering that each composite characteristic will require the application of micro-mechanical models, methods are also used to determine the strength stress in notched specimens by using the micro-mechanical models [10]. The 3D finite element model of composite laminates for progressive damage analysis based on continuum damage mechanics was developed [11][12][13].…”

In this paper, the application requirement of the Residual Property Model based on the decrescent exponential function is reduced to only one mechanical test data. For this, by using Creager and Paris's elastic stress field equation in front of the blunt elliptical hole, the theoretical radius was chosen for the tip curvative and the maximum stress in the load direction at the tip is ensured to be equal the fracture toughness. Thus, the workload of the model is reduced by making the u exponent in the e-u function dependent on the geometric correction factor and the crack length. It was applied to the laminated composite specimens with three-point bending and the specimens including circular hole, and critical fracture stress values close to actual values were achieved.

A carabiner is a fall protection safety tool that is used in various outdoor and indoor activities, most known usage is at climbing and high-risk work related to elevation. A standard carabiner is capable to withstand at least 7 kN of static load. In this study, we only observe how carabiners respond in certain static loads by using simulation software and comparing the result with the standard of carabiners. We use F1956-13 as a standard of the test procedure, and aluminum alloy 6061 as the material. After the study from simulation result, it shows that stress and deformation change linearly with loads. But the safety factor has different behavior, after the load applied increases over 1 kN the slope decreases significantly, and the safety factor is around 0,17 at 7 kN applied load. Besides that, we understand that design analysis by simulation is a good method to obtain the optimal geometry, or shape of the model, but computational simulation cannot replace physical mechanical tests.
