Modeling of fatigue behavior based on interaction between time- and cyclic-dependent mechanical properties

A general constitutive equation was established using the theory of viscoelasticity in order to consider the interaction of the time- and cyclic-dependent mechanical properties of laminated composites. This equation was solved for two specific loading patt ...

Load history effects in fibre-reinforced polymer composite materials

Abdolvahid Movahedirad

Today, it is widely accepted that fatigue is one of the most common failure mechanisms in structural components, and pure static failure is rarely observed. Engineering structures are subjected to complex mechanical fatigue loading histories, which cause d ...

Stress ratio effect on tension-tension fatigue behavior of angle-ply GFRP laminates

Thomas Keller, Anastasios Vassilopoulos

The effect of the stress ratio (R = sigma(min)/sigma(max)) on the fatigue behavior of (+/- 45)(2s) angle-ply glass/epoxy composite laminates was investigated by comparing their mechanical, thermal, and optical properties under the stress ratio of 0.5 with ...

Temperature effect on fatigue behavior of basalt fiber-reinforced polymer composites

Thomas Keller, Anastasios Vassilopoulos, Xing Zhao, Xin Wang

In this study, the temperature effect on the static and tension–tension fatigue behavior of basalt fiber‐reinforced epoxy polymer (BFRP) composites is investigated. The S–N curves, energy dissipation, stiffness degradation, and displacement increment with ...

Creep effects on tension-tension fatigue behavior of angle-ply GFRP composite laminates

Thomas Keller, Anastasios Vassilopoulos, Abdolvahid Movahedirad

Angle-ply (±45)2S glass/epoxy composite specimens have been subjected to pure creep and tension-tension constant amplitude fatigue loading interrupted at max by creep intervals lasting for 2 or 48 hours in order to examine the effects of creep loading on ...

3D laser shock peening as a way to improve geometrical accuracy in selective laser melting

Roland Logé, Nikola Kalentics, Andreas Burn, Michael Cloots

One of the major drawbacks of selective laser melting (SLM) is the accumulation of tensile residual stresses (TRS) in the surface and subsurface zones of produced parts which can lead to cracking, delamination, geometrical distortions, and a decrease in fa ...

Effects of load interruption on the fatigue life of GFRP composites

Thomas Keller, Anastasios Vassilopoulos, Abdolvahid Movahedirad

The effect of cyclic loading interruption on the fatigue behavior of angle-ply (±45)2S glass/epoxy composite laminates was investigated by comparing the obtained results of continuous- and interrupted loading patterns. Continuous fatigue experiments were p ...
