Method & Evidence

AimTo numerically model and compare the progressive damage and ultimate load-bearing capacity of multi-bolted joints made from different FRP laminates (basalt, carbon, glass) with varying stacking sequences.

MethodNumerical simulation using a custom finite element model.

ProcedureA finite element model was developed to simulate the progressive damage of multi-bolted joints in FRP laminates. The model incorporated micro-structural stress-strain localization and a constituent-scale failure criterion (Huang's criterion). The simulation was validated against existing experimental data.

ContextStructural engineering, composite materials, mechanical joints.

Strengths & Limitations

Strengths

+Development and validation of a custom finite element model for progressive damage analysis.
+Comparison of multiple FRP material types and joint configurations.

Limitations

The numerical model's accuracy depends on the input parameters and the chosen failure criteria. Real-world manufacturing variations can affect actual performance.

Reliability & validity

The study's validity is supported by validation against experimental data. Reliability would depend on the robustness of the finite element model and the accuracy of the input material properties and failure criteria.

Think critically

To what extent do the numerical findings on basalt-FRP strength in double-bolted joints translate to real-world performance, considering factors like manufacturing tolerances and environmental conditions?

Design Principles

"Material selection for composite joints should consider the specific load transfer mechanism (e.g., single vs. double bolting) to leverage the full potential of different fiber types."

This finding is crucial for material selection in structural design, suggesting basalt-FRP as a viable and potentially more cost-effective alternative to traditional carbon or glass fibers for certain applications. It allows designers to explore new material combinations without significant compromise on load-bearing capacity in specific joint designs.

What This Means for Your Design

This research shows that for some types of bolted connections (specifically, those with two bolts), using basalt fibers in composite materials can be just as strong as using carbon or glass fibers.
