Optimization of energy absorbing sandwich panel

with different foam geometry with and without foam under pseudo-static and dynamic load with ls dyna software 

Optimization of energy absorbing sandwich panel

Analytical modeling is the metal honeycomb in the sandwich panels.

Investigation of energy absorption properties of metal honeycomb houses and development of analytical models to investigate the energy absorption behavior of honeycomb houses using ls dyna software is one of the important issues to be studied.
It also aims to investigate the energy absorption properties of metal honeycomb houses

Review the sandwich panel and its applications

Sandwich Panel
Sandwich Panel [1] or Aluminum Composite Panel (ACP) as well as Aluminum Composite Materials (ACM) are composed of lightweight composites comprised of two layers bounded at one end and a layer between them. Insulated (like a hamburger sandwich on which the hamburger bread is coated on both sides) This insulation is soft and flexible. Sandwich panels are made from materials such as polyurethane, polystyrene, stone wool and glass wool.

Figure 1-1 is an example of a sandwich panel

Application of Sandwich Panel
Use of sandwich panels in a variety of cold houses and refrigeration industries. Workshop offices, sanatorium, sanatorium, clinic, field office, mobile repair shop, security post, one- and two-story villas - relief units in critical times such as earthquakes, niches, walls and ceilings in production halls. , Office Buildings & Hotels, Dormitories, Containers Sandwich Panel Application in Multi-Wall Tanks, Nursery Coverage, Homes & Villas, Industrial Sandwich Panel, Nursery Coverage, Club & Cold House, Critical Assistance Units such as Earthquake, Residential Buildings , Grain warehouses, schools and clinics Mobile, cold meat and dairy, mobile homes and caravans, indoor swimming pools, sports halls, walls and roofs of industrial buildings, walls and ceilings and walls of internal divisions in the factory and office rooms. Sandwich panels also have a variety of uses in a variety of industries, including construction of containers, containers, fixed and removable refrigerated receptacles, prefabricated structures and houses, temporary accommodation camps, niches, steel structures, space structures, warehouses and docks, sports complexes, Industrial and manufacturing plants, industrial and semi-industrial cold stores.

Properties of Sandwich Panel
Among its properties are the following:

1: High energy insulation 2: Lightweight compared to other materials 3: Very low cost compared to traditional materials 4: Washable 5: Easy to install and run 6: Various colors 7: Proper sound insulation 8: High resistance to earthquake shear forces 9: Extended shelf life
