Experimental and Numerical Study of Rubber Intermixed Ballast System Subjected to Monotonic and Cyclic Loading
Quarried natural rock aggregates are the most demanded type of railway ballast worldwide, attributed to their favourable physical, geotechnical and mechanical properties. After a certain period of operation and fatigue under repeated loading, degraded ballast requires replenishment with freshly …

Non-linear finite element analysis of reinforced concrete panels and infilled frames under monotonic and cyclic loading. Structures under plane stress loading are analysed up to and beyond the peak load. Non-linear material properties including cracking, crushing and the non-linear behaviour at the interface of members are considered.
… to simulate the behaviour of infilled frames and plane stress reinforced concrete members under the action of monotonic and cyclic loading has been developed. Steel is modelled as a strain hardening plastic material, and in the concrete model cracking, yielding and crushing are considered. The …

Experimental evaluation of monotonic and cyclic fracture behavior using disk-shaped compact tension test and released energy approach
… of fracture behavior of asphalt concrete under monotonic and cyclic loading using the disk-shaped compact tension (DC(T)) test and a released-energy based approach. The standard DC(T) test was revised to facilitate both monotonic and cyclic loading tests, including some modifications of the test …

Development of a phenomenological constitutive model for fracture resistance degradation of asphalt concrete with damage growth due to repeated loading
… the asphalt concrete (AC) layer, such as joints and cracks in an underlying layer, induce higher stress concentration than the designed strength. Stress concentration in the vicinity of discontinuities accelerates distress on the AC layer. Repeated traffic and environmental loading applied to the …
