This will reduce the cost of transporting empty containers while respecting the standards containers in force size, strength, and devices used for handling and securing the means of road or rail shipping.   This container will be the feature of reconfigurable and compactable in length so as to reduce its volume vacuum and thus to optimize its size, storage, transport (land and sea).   Study the behavior of a lightweight material selected under monotonic loading in different environments and service (high and low temperatures, humidity, shock ...) containers in their new form.  Keywords:  container, adjustable, son container, mother container, lightweight material, monotonic loading, intermodal transport.   1   Introduction Since 1956 the year of the container invention we are living a revolution in our life. The container made shipping very cheap, and by doing so changed the shape of the world economy. The total cost of a container multimodal transport includes land transport and also the transport of the empty container[1]. Cost transport depends on volume of goods and this rule is available for container transport. Transporting a full container seems cost-efficient, while moving and storing an empty one certainly is  52 A. Abdallah et al.  not. Cont’able presents solution for this. A certified adjustable container made with composite material is currently being developed. The new container made of composite material with corrosion resistance weighs 25 % less than a steel con-tainer and can be transformed from a 20 feet to a 40 feet container in few minutes. Many advantages results from the new design of the container. It will be adapted to the needs of transporter. Secondly when the container is empty so we can re-duce the volume to became a 20 feet container and for land transport, it well be carried by a middle size truck and we don’t need a trailer. Thirdly loading of the new container will be easier. in fact we can reduce time of loading empty con-tainer in ships. As a result all stakeholders in the international transport chain will find interest and in particular: - Chargers: exporters, importers, manufactures, distributors - Shipping companies; maritime carriers: “deep sea”; “Short sea” carriers. - Road carriers - Intermodal operators. - Port authority with less space for storing. - Control authority such as customs administration with non intrusive control (scan). 2   Scientific Context The innovative project called "Cont'able" and which is the subject of our research is to design and manufacture a new type or model container ISO-compliant stan-dards used for multimodal transport of goods. This container will be the feature of reconfigurable and compactable in length so as to reduce its volume vacuum and thus to optimize its size, storage, transport (land and sea). The PhD project aims to study the behavior of a lightweight material selected under monotonic loading in different environments and service environments (high and low temperatures, humidity, shock ...) containers in their new form (Fig 1).   The use of a composite material we will firstly a reduction in weight of the va-cuum container [2,5] and also facilitates the movement of these two removable compartments.   So we will have a lighter container (up to 25% weight gain) and the loading ca-pacity of container ships increased in terms number of containers that transport.   An important aspect to note is made that the new container helps preserve the en-vironment by reducing the number of empty trips thereby reducing CO2 emissions into the atmosphere. (Divide by at least two empty journeys).    A New Design of an Adjustable Length Container with a New Lighter Material 53  Fig. 1  Technical solution 1  :fixed block length of 20 feet. 2 : left mobile compartment 3 : right mobile compartment The curb weight of a conventional 40-feet container varies between 3.5 and 4 tones and that depending on the year of construction and the manufacturer [6]. For our model we hope does not exceed 4.5 tones for the first phase and 3.5 tons for the second phase , that is to say after using components and lighter composite ma-terials. The use of other materials must reflect a different stress resistance of the roof of the container and which is equal to 300 kg on a surface of 60 cm * 30 cm .   Indeed, in practice the containers are stacked on top of each other and may have a situation where the container will have to bear the weight of other containers 4 and 5 .   The lifetime of a conventional container 15. From our model would be made with mechanisms and mechanical equipment , is provided for a service life of 10 years this model .   The average loading capacity of conventional containers of 20 feet or 40 feet by weight are respectively 27 and 30 tones and maximum values were 29 and 32 tons.   3   Steel Adjustable Container Design  3.1    Design of Different Parts The innovative container consists of a central element, characterized in that said central member comprises a fixed central portion (mother container) corres-ponding to an ISO container of 20 feet dimension and two integral parts  54 A. Abdallah et al.  (son containers) of the fixed central part, movable in the lengthwise and deploya-ble on either side of the central fixed part, and allowing the processing dimension of the container 20 feet container 40 feet in dimension. Fig 2 Fig. 2 Sketch of the technical solution 1  :fixed block length of 20 feet. 2 : left mobile compartment 3 : right mobile compartment A solution is proposed for this system variable structure. The following images show the different views for a 3D model.Fig 3 Fig. 3 3D view of adjustable container  A New Design of an Adjustable Length Container with a New Lighter Material 55  In the following two cases, the adjustable container has external standardized dimensions ISO 668: • The closed cases (20 feet container) 6058 x 2438 x 2591 mm,(Fig 4) Fig. 4 Adjustable closed container case (20 feet)   •   The open cases (40 feet container) 12192 x 2438 x 2591 mm.(Fig 5) The lengths of the adjustable container consider a real challenge as the standard length of the 40 feet container larger than the 20 feet container. So we had to de-sign an appropriate solution find all the dimensions in both cases. Fig. 5 Adjustable opened container case (40 feet) a.   Mother Container: The fixed central container called mother container, has dimensions 6058 x 2438 x 2591 mm and has a wooden floor which treated and resistant (eg Mahogany). A guide-spring system is used to position the floor on two different levels. The mother container is steel S355MC and the eight corners are made of carbon steel alloy. Fig 6
