Analysis of blast load on a reinforced concrete column in the time domain

open access: yesMATEC Web of Conferences, 2017
This paper is concerned with simulation of the blast load on a reinforced concrete column for different design options with the use of the finite element technique in LS-DYNA. Calculations were made with regard to the gravity load.

On the numerical modelling of bond for the failure analysis of reinforced concrete [PDF]

open access: yes, 2017
The structural performance of reinforced concrete relies heavily on the bond between reinforcement and concrete. In nonlinear finite element analyses, bond is either modelled by merged, also called perfect bond, or coincident with slip, also called bond ...

Modelling aeronautical composite laminates behaviour under impact using a saturation damage and delamination continuous material model [PDF]

open access: yes, 2010
We show that the behavior of T700/M21s and T800/M21s composite panels are affected by the influence of strain rates together with local shear and crush punch or global flexural strengths of the structure.

A Computational Approach for Probabilistic Analysis of Water Impact Simulations [PDF]

open access: yes
NASA's development of new concepts for the Crew Exploration Vehicle Orion presents many similar challenges to those worked in the sixties during the Apollo program. However, with improved modeling capabilities, new challenges arise.

دراسة استجابة وسلوك الأعمدة البيتونية المسلحة المعرضة لحمل انفجاري والمطوقة بشرائح البوليميرات المسلحة بالألياف الكربونية (CFRP)

open access: yesمجلة جامعة دمشق للعلوم الهندسية, 2023
استدعى زيادة الخطر المرتبط بالهجمات الإرهابية على المنشآت زيادة الأبحاث العلمية المتعلقة بتقييم الاستجابة الديناميكية للمنشآت التي من الممكن أن تتعرض لهذا الخطر، والذي قد يؤدي إلى الانهيار المتتالي للمنشأ.
