Time-dependent brittle creep-relaxation failure in concrete

Creep: Time‐dependent brittle deformation in rocks

Brittle creep, damage and time-to-failure in rocks

We propose a numerical model based on static fatigue laws in order to model the time-dependent damage and deformation of rocks under creep. An empirical relation between time-to-failure and applied stress is used to simulate the behavior of each element of our finite element model. We first review available data on creep experiments, in order to study how the material properties and the loading...

Special Time Series Prediction: Creep of Concrete

This paper presents an algorithm, different from the classical time series, specialised in extracting knowledge from time series. The algorithm, based on Genetic Programming, enables the dynamic introduction of non-terminal operators shaped as mathematical expressions (operatorexpression) that works as an unique node for the purpose of genetic operations (crossover and mutation). A new characte...

Effect of Cured Time on Creep of Lightweight Aggregate Concrete

Creep and shrinkage are such properties that will occur in concrete when they are under load and exposed to surrounding. Since this property will cause deformation which may decrease the design strength of the concrete, it is necessary to do have more knowledge on this phenomenon. So, we will study the effect of creep on 7 and 14 days of cured time of specimens which sealed or unsealed will be ...

Time dependent properties of bovine meniscal attachments: stress relaxation and creep.

It has been suggested that the success of a meniscal replacement is dependent on several factors, one of which is the secure fixation and firm attachment of the replacement to the tibial plateau [Chen, M.I., Branch, T.P., et al., 1996. Is it important to secure the horns during lateral meniscal transplantation? A cadaveric study. Arthroscopy 12(2), 174-181; Alhalki, M.M., et al., 1999. How thre...
