Overview

Aero­space

LS-DY­NA is wide­ly used by the aero­space in­dus­try to sim­u­late bird strike, jet en­gine blade con­tain­ment, and struc­tur­al fail­ure.

Aero­space ap­pli­ca­tions in­clude:

  • Blade con­tain­ment
  • Bird strike (wind­shield, and en­gine blade)
  • Fail­ure analy­sis

Au­to­mo­tive Crash­wor­thi­ness & Oc­cu­pant Safe­ty

LS-DY­NA is wide­ly used by the au­to­mo­tive in­dus­try to an­a­lyze ve­hi­cle de­signs. LS-DY­NA ac­cu­rate­ly pre­dicts a car’s be­hav­ior in a col­li­sion and the ef­fects of the col­li­sion up­on the car’s oc­cu­pants. With LS-DY­NA, au­to­mo­tive com­pa­nies and their sup­pli­ers can test car de­signs with­out hav­ing to tool or ex­per­i­men­tal­ly test a pro­to­type, thus sav­ing time and ex­pense.

Spe­cial­ized au­to­mo­tive fea­tures in­clude:

  • Seat­belts
  • Slip rings
  • Pre­ten­sion­ers
  • Re­trac­tors
  • Sen­sors
  • Ac­celerom­e­ters
  • Airbags
  • Hy­brid III dum­my mod­els
  • In­fla­tor mod­els

Earth­quake En­gi­neer­ing – Soil-Struc­ture In­ter­ac­tion

Large civ­il struc­tures such as con­crete dams, nu­clear pow­er plants, high-rise build­ings and bridges are mas­sive enough that their vi­bra­tion due to earth­quake ex­ci­ta­tion af­fects the mo­tion of the soil or rock sup­port­ing them, which in turn fur­ther af­fects the mo­tion of the struc­ture it­self. This in­ter­ac­tion be­tween the struc­ture and the soil needs to be mod­elled ac­cu­rate­ly in or­der to de­sign earth­quake re­sis­tant struc­tures and to cor­rect­ly eval­u­ate the earth­quale safe­ty of ex­ist­ing struc­tures.

Met­al Form­ing

One of LS-DY­NA’s most wide­ly used ap­pli­ca­tions is sheet­met­al form­ing. LS-DY­NA ac­cu­rate­ly pre­dicts the stress­es and de­for­ma­tions ex­pe­ri­enced by the met­al, and de­ter­mines if the met­al will fail. LS-DY­NA sup­ports adap­tive remesh­ing and will re­fine the mesh dur­ing the analy­sis, as nec­es­sary, to in­crease ac­cu­ra­cy and save time.

Met­al form­ing ap­pli­ca­tions in­clude:

  • Met­al stamp­ing
  • Hy­dro­form­ing
  • Forg­ing
  • Deep draw­ing
  • Mul­ti-stage process­es

Mul­ti­physics

Pur­su­ing its ob­jec­tive of solv­ing cou­pled mul­ti­physics prob­lem, LS-DY­NA R7 in­cludes three new solvers :

  • In­com­press­ible CFD
  • Elec­tro­mag­net­ics
  • CESE/­ Com­press­ible CFD and Chem­istry

Oth­er

Oth­er ap­pli­ca­tions in­clude:

  • Drop test­ing
  • Can and ship­ping con­tain­er de­sign
  • Elec­tron­ic com­po­nent de­sign
  • Glass form­ing
  • Plas­tics, mold, and blow form­ing
  • Bio­me­chan­ics (heart valves)
  • Met­al cut­ting
  • Fail­ure analy­sis
  • Sports equip­ment (golf clubs, golf balls, base­ball bats, hel­mets)
  • Civ­il en­gi­neer­ing (off­shore plat­forms, pave­ment de­sign)
