this paper presents a novel formulation and numerical solutions for adhesively bonded composite joints with non-linear (softening) adhesive behaviour. the presented approach has the capability of choosing arbitrary loadings and boundary conditions. in this model adherends are orthotropic laminates that obey classical lamination theory. the stacking sequences can be either symmetric or asymmetri...

In this study we tried to consider effect of vertical component of near zone earthquake (10 to 15 km far from fault) such as Kobe 1995, Northridge 1994, Loma prieta 1989 and Chichi 1999 on a concrete cable bridge by a 320m span in the middle which was built on different type of soils. The SAP software (version14) was selected because I should have done linear and non-linear time history anal...
the most important postharvest disorder of cut gerbera is stem bending disorder, which occurs below the capitulum. stem strength and lignification is one of important phenomenon and causes of gerbera stem bending. therefore, this experiment was conducted to evaluate the effects of salicylic acid (sa) on phenylalanine ammonia-lyase enzyme activity (pal), as an important enzyme in phenylpropanoid...
Cytoskeletal polymers play a fundamental role in the responses of cells to both external and internal stresses. Quantitative knowledge of the mechanical properties of those polymers is essential for developing predictive models of cell mechanics and mechano-sensing. Linear cytoskeletal polymers, such as actin filaments and microtubules, can grow to cellular length scales at which they behave as...
Geometry constructions of honeycomb core are finding increasing use because of their relative advantages over other structural materials in terms of improved stability, high stiffness to weight and strength to weight ratios. It provides an efficient solution to increase bending stiffness without significant increase in structural weight. However, honeycomb carton, as a new product of paper hone...
We used adaptive umbrella sampling on a modified version of the roll angle to simulate the bending of DNA dodecamers. Simulations were carried out with the AMBER and CHARMM force fields for 10 sequences in which the central base pair step was varied. On long length scales, the DNA behavior was found to be consistent with the worm-like chain model. Persistence lengths calculated directly from th...
در فصل اول ابتدا، سیستم پانلهای ساندویچی بتنی معرفی شده و سپس مشخصات مطالح تشکیل دهنده مورد بررسی قرار گرفته است. در فصل دوم، تحقیقات بعمل آمده روی عملکرد پانلهای ساندویچی بعنوان اعضای سازه ای، مورد بررسی و مطالعه قرار گرفته است. در فصل سوم تحقیقات تجربی انجام شده بر روی عملکرد اعضای خمشی تشکیل شده از پانلهای ساندویچی بتنی توسط دکتر رسول احمدی [4] بصورت کامل شرح داده شده است. در فصل چهارم عملکر...
